Can't trace orchestrator function execution in AI logs - customDimensions.prop__instanceId always null

[kwill-MSFT]

I am trying to use https://docs.microsoft.com/en-us/azure/azure-functions/durable/durable-functions-diagnostics?tabs=csharp to trace my Powershell durable functions, but the instanceId is always* null so these queries don’t work, and it is extremely difficult to trace a full orchestration execution.

• instanceId does seem to be populated when an activity function exceeds the 10 minute timeout period.
