Distributed Tracing not working when using Service Bus topics #1287

Closed dicksongwong closed 4 months ago

dicksongwong commented 4 months ago

I'm building microservices on Azure Functions 4.0 that communicate via Azure Service Bus. The operation id is carried through from one azure function to another when using service bus queues but once the message is published to a topic, the operation id resets for the subscriber and breaks the distributed tracing. Is this the expected behavior? Any workaround?
