            Trouble with On-Behalf-Of flow with standalone Blazor WASM, AAD, .NET Core 6 Web API calling MS Graph
            Asked 2022-Mar-23 at 00:09

            I have a standalone Blazor WASM site (client), a separate .NET 6 web API (server) with protected endpoints and I'm trying to call MS Graph from the API.

            I've read just about every article I could find on the configuration required to make this work and I'm stuck with the incremental consent failing. I get the following error when trying to access a server API which uses MS Graph:

            Error acquiring a token for a downstream web API - MsalUiRequiredException message is: AADSTS65001: The user or administrator has not consented to use the application with ID '[redacted]' named '[redacted]'. Send an interactive authorization request for this user and resource.

            Configuration...
            1. Created AAD app for Web API (server), added secret for Graph configuration, set the app URI and created access_as_user scope under "Expose an API" in AAD.

            2. Added the client ID (from the following step) to the knownClientApplications section in the manifest for the server app registration in AAD.

            3. For API Permissions I added Graph scopes User.Read, User.Read.All, and Group.Read.All and provided admin consent in the AAD UI.

            4. Configured appsettings.json in the API to add the Graph API BaseUrl and above scopes from step 2 along with the correct AzureAD domain, TenantId, ClientId, and ClientSecret values for MSAL to function.

            5. Configured MSAL on the server:

            The issue here is use of the AddMicrosoftGraph method when the API application is being built.

            The GraphServiceClient created by AddMicrosoftGraph will have default access to delegated permissions which are assigned to users as opposed to application permissions which are assigned to applications. This is why the MsalUiRequiredException is being thrown which is usually resolved by prompting the user to login.

            You can read more about delegated vs application permissions here.

            What you can do instead is use the AddMicrosoftGraphAppOnly method to create a GraphServiceClient that will use credentials specific to your API to retrieve the relevant data needed from the Microsoft Graph API.

            as noted here regarding pouchDB Security, I tried using pouchdb-authentication when it was actively maintained and went another route due to multiple issues (I don't recall specifics, it was 6 years ago).

            AWS Object Lambda Access Point timing out when writing response when run from within VPC
            Asked 2022-Jan-13 at 13:39

            I've got an AWS Object Lambda Access Point. (These are sort of like a proxy lambda function which can intercept S3 requests and transform them.) It runs fine when not run inside a VPC (so I think IAM is fine). A later iteration will want to access private resources so I want it running inside a VPC.

            The flow of one of these lambdas (at least when transforming a GET request) is:

            1. Get invoked
            2. Download the object that was requested using a HTTP client (you get a pre-signed URL to grant access (getObjectContext.inputS3Url in the payload))
            3. Do your transformation
            4. Write the result using s3.Client.WriteGetObjectResponse

            It's the last step that isn't working for me.

            In my VPC I've added a gateway endpoint for S3 (for S3 either gateway or interface endpoints are supported; gateways are free. This works fine to fetch the object (step 2), I can download the object and work on it. I think that download happens through the gateway endpoint. So far so good.

            But after doing the processing it times out when trying to write the response (step 4). In the logs it looks like this:

            ...

            ANSWER

            Answered 2022-Jan-13 at 13:39

            The short answer is: You can run your object lambda function in a VPC as long as you allow it to route to s3-object-lambda..amazonaws.com through the internet, e.g. through a NAT gateway. You were on the right track and basically figured it out in your question already.

            The S3 gateway interface endpoint is necessary to enable download of the input object.

            When writing the result, the request goes to s3-object-lambda, which is technically a different service than S3 (at least on network level). AWS currently doesn't provide an interface endpoint for s3-object-lambda and the S3 gateway endpoint doesn't cover it either (which can be verified by comparing the IP address WriteGetObjectResponse request goes to and the routes created by the gateway endpoint).

            So the only way is to route WriteGetObjectResponse requests via opened access to the internet. For future reference, one way to set this up is with a NAT gateway. Quoting AWS docs:

            • The NAT gateway must be in a public subnet with a route table that routes internet traffic to an internet gateway.
            • Your instance must be in a private subnet with a route table that routes internet traffic to the NAT gateway.
            • Check that there are no other route table entries that route all or part of the internet traffic to another device instead of the NAT gateway.

            In other words:

            • Provision a public NAT Gateway in a public subnet and allocate it an elastic IP
            • Make sure the public subnet has an internet gateway and the default route (0.0.0.0/0) points to it.
            • Set up a default route (0.0.0.0/0) from the subnet hosting your lambda and point it to the NAT Gateway.

            You're right that a NAT Gateway is priced by the hour, unfortunately, and you need one per subnet.

            In theory, you could at least limit the egress with a security group to IP addresses of the s3-object-lambda service, but I'm not aware these IP ranges are published anywhere.

            How can I prevent java.net.http.HttpClient from making an upgrade request?
            Asked 2022-Jan-12 at 11:05

            Upon making a call from a Java project to a Python rest API, I am met with an error that states "Unsupported upgrade request."

            I'm making a simple GET request from Java, to the endpoint written in Python, and at some point Java decides it wants to request to upgrade the connection to a websocket. My issue is, I never reference websockets in my Java project whatsoever, and when I debug and look at the value of headers in the request, it does not show any headers at all, but at some point before it hits the network it decides it wants to do an upgrade request. I haven't sniffed my own traffic to confirm the existence of the header yet; but the problem does not exist when I use OKHTTP instead of java.net.http.HttpClient

            This code results in the Unsupported Upgrade Request error returned by the Python API.

            Requests shouldn't be upgraded to websocket - but the default for the HttpClient is to request an upgrade to HTTP/2.

            If you don't want the HttpClient to request an upgrade to HTTP/2 you can set the version in the request to Version.HTTP_1_1, or set the default version in the HttpClient to Version.HTTP_1_1.

            Nested logic app retries - parent throwing 504
            Asked 2021-Nov-29 at 16:47

            I have a nested logic app which takes some time for 4 retries in case of a failure. According to the documentation, the default HTTP timeout is 100 seconds. I'm able to increase the HTTP client timeout value in my code which triggers the parent logic app, but in case of a failure in the child logic app, it is retried 4 times and takes much longer. Meanwhile, the parent logic app responds with a 504 (gateway timeout). There are some more actions to take care of after the child logic app returns a response, so I can't make it asynchronous and return 202 to the code trigger. Is there a way to increase the timeout in the nested logic app without making it async?

            E.g. - My nested logic app retried 4 times and failed after 4 minutes

            However, my code already receives a response of 504 after 2 minutes 9 seconds of triggering the parent logic app

            The HTTP client which triggers the parent logic app has a timeout of 20 minutes. I verified that this timeout value is working, because without it, we were receiving the timeout reponse in 1 minute 40 seconds (100 seconds), which is default HTTP trigger timeout. I'm under the impression that if the nested logic app also doesn't respond within 100 seconds of being triggered, the parent throws a timeout because it didn't receive a response. Is there a way to work around this?

            It might not be possible without asynchronous patterns or async calls but One of the workarounds can be using HTTP+Webhooks where you can set the timeout value.

            As per the comment, there is an excellent blog post by Andrew Lock that talks about this.

            TL;DR

            You'll need to use IHttpContextAccessor to resolve the scoped service and get the instance you want.

            Example

            All credit for this example should be given to Andrew Lock and his blog post, but for quick reference readers of this question, you need to inject the IHttpContextAccessor into your DelegatingHandler and use that to access the correct scoped service.

            Answered 2021-Oct-19 at 08:20

            Okay; it has developed your problem is that when the server requests your client-cert/auth, it specifies a CA list that doesn't include the CA(s?) used by your cert-and-chain, even though when presented with your cert-and-chain the server accepts it. After commenting about writing a wrapper KeyManager, I realized it would be easy enough to test, and the following example works for me to send a client cert different from what the server asked for. I used SSLSocket directly for simplicity, but anything (like OkHttp) using the same SSLContext or SSLSocketFactory should work. Tested in 8u301 (but I can check some others if you want) against OpenSSL commandline, which lets me request client cert for CA X but when I submit a cert from CA Y it only logs the verification error without aborting the connection.

            Domain Driven Design: Define boundaries from Domain Model
            Asked 2021-Oct-06 at 07:49

            I am working on a project and I am trying to utilize the concepts of Domain Driven Design.

            I have the following domain model: (it is simplified for this question)

            Let me explain the system first.

            This system is for monitoring data coming from gateways. In this case there are two gateways, but there might be more in reality. Each gateway has its own implementation, so its own entities.

            An example of the system is as follows:

            A company has a project to monitor ship data.

            So they have two gateways. A gateway with type Field-Device-Gateway and a gateway with type HTTP-Client-Gateway.

            The first gateway (field-device-gateway) can have multiple field devices. A field device is a small device onboard on a ship. This device receives all data coming from devices on board of the ship. This is through a source (like an address) that has to be setup in the system.

            The second gateway (http-client-gateway) can have multiple HTTP clients. Each client may have multiple routes.

            So, a gateway also has variables. A variable is a configuration for getting a specific set of data. So, on the field-device-gateway might be a variable specifying to get integer data from a specific device, from a specific field device source, from a specific field device.

            The system will make a request to the field device with the new variables. The field device then knows what data to send. It will be received by the system and stored in the database.

            So, what am I asking?

            Currently, everything is coupled. I need to define boundaries and then aggregates, but I just don't know where to start.

            If I would not create boundaries, this will just become an enormous coupled mess and makes it hard to make aggregates.

            So, what would the boundaries be? And what about the aggregates, are there even aggregates? Is everything its own aggregate?

            And if everything is its own aggregate, how do I enforce some business logic like: A variable can only exist if there is a gateway, project and company.

            ...

            ANSWER

            Answered 2021-Oct-06 at 07:49

            Before thinking about boundaries, you have to go back to domains and subdomains.

            The problem space is your domains (and subdomains) and your solution space is your Bounded Contexts.

            The first important issue in the application of the DDD in a project is to identify your sub-domains and in particular to divide them into the 3 following "families":

            • Core Domain
            • Supporting Subdomain
            • Generic Subdomain

            This cutting is driven by this sub-domain families and by the domain expert.

            A Bounded Context is a language boundary where context is king. We only know the meaning of a concept thanks to its context (which is also a cultural context).

            How to avoid making mistakes in the division of Bounded Contexts?

            • When there are technical or architectural considerations
            • When you try to split a Bounded Context to distribute tasks to free developers
            • If you have two objects that don't have the same definitions, then they must be in two different Bounded Contexts

            If you think to all this, you may easily separate your objects (your language) into these Bounded Contexts.

            For your Aggregate's problem :

            • Try to decide for each class if it is an Entity or a Value Object (or Domain Service but try to avoid).
            • Your Aggregates are "some" of your main Entities which can drive other Entities
