I am using PouchDB and CouchDB in an ionic application. While I can successfully sync local and remote databases on Chrome and Android, I get unauthorized error on Safari / iOS when I run the sync command. Below is a simplified version of my database service provider.

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:

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.

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?

I'm attempting to set up our Blazor Server application to use a custom delegating handler that will attach a bearer token to all outgoing requests to our APIs. The delegating handler uses a token service that handles the retrieval of the token as well as the process for refreshing it if it's expired. The code looks like this:

On my local machine, I want to use cURL as an HTTP client like so:

I am building a simple REST API package using cURL and would like to catch an error and then return a view. I am able to throw an error if I dd($e) but if I try and return a view it just continues with the code after the catch function. Shouldn't PHP kill the process and just go to the login view?

EDIT I'm able to build my OkHttp client to where it includes both the client cert in the Client.SSLContext.KeyManager, and the trusted certs in the Client.SSLContext.TrustManager

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.
