azure webjobs sdk ===. |branch|status| |---|:---:| |master|[build status] |dev|[build status] |v2.x|[build status] the azure webjobs sdk is a framework that simplifies the task of writing background processing code that runs in azure. the azure webjobs sdk includes a declarative binding and trigger system that works with azure storage blobs, queues and tables as well as service bus. the binding system makes it incredibly easy to write code that reads or writes azure storage objects. the trigger system automatically invokes a function in your code whenever any new data is received in a queue or blob. in addition to the built in triggers/bindings, the webjobs sdk is fully extensible, allowing new types of triggers/bindings to be created and plugged into the framework in a first class way. see [azure webjobs sdk extensions] for details. many useful

QUESTION
I'm using Azure function app, durable function for listing the subscriptions and go through each sub to do some process. My code was working fine until a few days ago that it stopped to work by giving this error:
...ANSWER
Answered 2021-Dec-02 at 19:59I was just trying to use SubscriptionClient for the first time and was running into this same issue, so I'm glad it wasn't just me.
I did find that they release a new version of the module on 2021-11-25, (see the release notes here: https://github.com/Azure/azure-sdk-for-python/releases/tag/azure-mgmt-subscription_2.0.0) and it lists a breaking change of "Removed operation group SubscriptionsOperations". The documentation doesn't seem to reflect this, and it's not clear what you're supposed to do instead to list all subscriptions.
I got it working by pinning azure-mgmt-subscription to 1.0.0.

I am trying to Create an Azure WebJob that runs a function every x seconds. I am following the tutorials on the Microsoft website and this example of how to use TimerTrigger with WebJobs on Github. However when I run locally my methods in Functions.cs do not seem to be running(no logging and break points aren't hit).

Answered 2021-Oct-24 at 09:34Finally, I figured out why our timed trigger wasn't firing in our webjob. After installing the following nuget packages,
I was able to get it to work using your function.cs
code in my .net framework 4.7.1 .
So To make our webjob with timer trigger work, we'll need to use 2.X or 3.X versions with the following packages:
Microsoft.Azure.WebJobs.Extensions -version 3.0.6
Microsoft.Azure.WebJobs.Extensions.Storage -version 3.0.1
Microsoft.Extensions.Logging -version 2.1.0
Microsoft.Extensions.Logging.Console -version 2.1.0
For reference check all the packages which i used in my environment :

I've noticed locally that the .edmx
file isn't generated when the project is built -- instead it's created when I start running the project using func start
.
Could this be a permissions issue (e.g. with the function not having write access to the storage blob)?
...ANSWER
Answered 2021-Oct-21 at 00:46I've found that the root issue is related to the Run From Package
setting.
This prevents the function app from generating the .edmx
file, so the solution is to either disable Run From Package
or to deploy the function with the .edmx
file pre-included.
From MSDN: Run From Package makes wwwroot read-only, so you will receive an error when writing files to this directory. (https://docs.microsoft.com/en-us/azure/azure-functions/run-functions-from-deployment-package)

There are a couple of stackoverflow posts which have similar issues but none of them have an authorization error problem.
I'm having problems running a Azure function with C# code with an eventhub trigger on Azure China. The same code runs fine on Azure global.

Any help is appreciated.

I have an Azure Function that has both Timer Trigger
and Service Bus Trigger
functions. In Portal Azure configuration of that AF, I have the correct storage account connection string AzureWebJobsStorage
. There were no changes in ARM of both resources, everything was working properly until few days ago. Now only Service Bus Trigger
functions are working, but not Timer Trigger
ones.
Connecting string to storage is 100% correct, I've even regenerated the access key.

Answered 2021-May-27 at 22:49There is a possible regression in the latest function host release(3.0.15733.0). Please set the app setting FUNCTION_EXTENSION_VERSION=3.0.15584.0 (previous function runtime version).

I'm currently deploying one Azure WebJob with a corresponding Web App to Azure via Azure DevOps. My Web Job startup is mostly taken from various examples like https://github.com/Azure/azure-webjobs-sdk/tree/dev/sample/SampleHost
...ANSWER
Answered 2021-Apr-22 at 09:44Is it possible, this combination doesn't work and I would need to deploy web app and web job seperately, or is there another problem around?
AFAIK, you do not need to deploy web app and web job separately.
If we deploy one Azure WebJob with a corresponding Web App, we need to create the WebJob project by right clicking on your Web App and choosing:
QUESTION
We are using Azure blob trigger where we can able to process the files locally.
But after we publish the code in the Azure Portal, it started throwing the below error.
...ANSWER
Answered 2021-Apr-14 at 14:45Please check if you set the correct Runtime version
when deploying azure blob trigger function
to azure portal
:
If the Runtime version
of your local azure function
is inconsistent with the Runtime version
of the azure portal
, it may cause the problem you mentioned.
Solution:
You can delete the deployed function, then set the correct Runtime version
and re-deploy the local function to azure portal
.
The problem mentioned in this article is similar to the error message you gave, you can refer to it.

Access the message data by using a method parameter such as string paramName. You can bind to any of the following types:
Object - The Functions runtime deserializes a JSON payload into an instance of an arbitrary class defined in your code.
string
byte[]
CloudQueueMessage
Not sure how you define the StudentMessage
class, but if you could meet your need by using string
type, you could consider use it.
QUESTION
I have an azure function with a ServiceBus Trigger running locally and on azure just fine. Suddenly, the Azure deployment started failing with the following stack trace:
...ANSWER
Answered 2021-Feb-11 at 14:56When I see goofy stuff like this, I like to verify what runtimes and SDKs I am running locally and what is running remotely. To do this, we need to log in to our service's Kudu portal:
If your service domain is hello.azurewebsites.net
, then go to hello.scm.azurewebsites.net
.
At the top of the site there is a "Debug Console" option. Click that and go to CMD and type in dotnet --list-sdks
and also dotnet --list-runtimes
If you are using nuget packages in the version 5 range, make sure your server has the v5 SDK/framework.
Also, stay consistent in your nuget packages. If you are using asp.net core 3.1, do not use v5 nuget packages. Make sure your packages are all v3.
I am going to link the information from your comment about not mixing .NET Core 3.1 and .NET5 packages when working specifically with Azure Functions. Apparently Azure Functions haven't been fully vetted with .NET5 which is why your server is only showing .NET Core 3.1.
