It has:
HTTP and blob triggers
configures otel to collect incoming and outgoing HTTP and function worker sources
it sends some custom spans from function invocations
it exports all logs, traces and spans to local aspire dashboard
What I see:
HTTP trigger works fine: spans and logs are exported as expected
Blob trigger does not produce any spans from the worker - even custom ones. It produces a bunch spans from the host, but none of them are related to the specific invocation (or not correlated to it)
It produces logs, which have trace-id, but there is no corresponding trace
Mysteriously, even the custom activity that works perfectly fine in the HTTP trigger becomes null inside blob trigger.
It also produces a bunch of host-level storage-polling noise, but I don't see any spans describing the triggered function
Expected:
Blob trigger is reported as a span on the host and custom activity is reported from inside the trigger code.
