Azure WebJobs SDK ServiceBus connection string 'AzureWebJobsAzureSBConnection' is missing or empty

Question

I created an Azure Function App in Visual Studio 2015. The App has a trigger for service bus queues. The app works perfectly when I run it locally. It is able to read the data f

Answer 1

Only environment variables are supported for app settings and connection strings.

You need to make sure that the environment variable AzureWebJobsAzureSBConnection is set on your Function's app settings in the portal:

and then once there, you need to add the AzureWebJobsAzureSBConnection variable with the proper connection string:

and then you can access this via code by:

Environment.GetEnvironmentVariable(name, EnvironmentVariableTarget.Process);

This will obtain the value from either the appsettings.json or the environment variable depending on where the function is being executed from, (local debugging or deployed on Azure)

Answer 2

It is able to read the data from the Service Bus queue (configured via a variable named AzureSBConnection) But it gives me the following error when deployed in Azure:

After you deployed your application to Azure Function, your application will read the connection string from environment setting. Currently, connection settings in appsettings.json will not update environment setting automatically. We could click [Configure app settings] button as @flyte mentioned to check whether the connection string is configured successfully. If not, you could add it manually in app setting box.

Note that my connection is called AzureSBConnection and not AzureWebJobsAzureSBConnection

Please go to [Integrate] page to check whether the [Service Bus connection] is configured successfully. If not, you could reset it by clicking the [new] link.
