Description

We have an in-process Azure Durable Functions project whereby we inject the Azure App Configuration Services and set up configuration for the app. What we are seeing is the durable function not coming out of a running state and the error message:

An invalid asynchronous invocation was detected. This can be caused by awaiting non-durable tasks in an orchestrator function's implementation or by middleware that invokes asynchronous code.

We have isolated this to Azure App Configuration service by creating a separate Durable Azure Function (see attached zip). It runs fine when the Azure App Configuration dependency is not there. However, when we tie it in, we get the failure.

For example, if you comment out line Program.cs line 60 the orchestration goes into a completed state else, it stays in a running state. We think maybe this is due to some async task which the Orchestration is detecting? We could not find an open issue on this or any related docs.
FunctionApp1.zip

Would there be a work around for this?

Expected behavior

We would expect the app configuration service background worker tasks to get the configuration data and check a sentinel to not interfere with a durable tasks ability to go to a status of completed.

Actual behavior

The durable task is not completing and stays in a running state.
