Issue with flow references #2

Closed bijuiv-ms closed 2 years ago

bijuiv-ms commented 2 years ago

When there are flow references in the application, I'm seeing the following null pointer issue in the logs and the trace is not getting forwarded from the referenced flow. Wondering if I'm missing something in the config?

I think the issue is when using flow references to sub-flows. It works when the flow-ref is to a private flow, but not a sub-flow. Is that a known limitation/expected behavior?

Sub-flows are a bit more complicated to handle and will require some additional instrumentation.

Might be an issue. I haven't tried it yet. Will spend some time this weekend to see what's going on. Thanks for reporting it.

Hi @rickbansal-mulesoft I am getting the same issue and wondering if you were able to fix it? Is it released in a newer version to use?
