Multithreaded execution was detected

[HardikAg22]

During our troubleshooting, we were able to see that when the durable function app was hosted on aks, then it started throwing the Multithreaded execution was detected error.

Below is the error:
4b2ff1b5-200a-5014-9174-1587041c34d0: Function 'JobMonitor (Orchestrator)' failed with an error. Reason: System.InvalidOperationException: Multithreaded execution was detected. This can happen if the orchestrator function code awaits on a task that was not created by a DurableOrchestrationContext method. More details can be found in this article https://docs.microsoft.com/en-us/azure/azure-functions/durable-functions-checkpointing-and-replay#orchestrator-code-constraints.

Hi @bhagyshricompany
This app is running in AKS container and not in func app. We are ok to share the portion of code in the orchestration for your reviews and recommendations.

Can you please share the mechanism to share the code.
