Issue with grpc 1.4.x agent not properly generating and propagating trace information

When upgrading gRPC from 1.3.x to 1.4.x the handling of trace identifiers no longer works. Meaning the trace information is always empty for gRPC 1.4.x but works fine for 1.3.x

Regardless of the version of grpc the tracing should work

Steps to Reproduce

Attached is a spring-boot application that has a grpc server and client. You can run the server setting the appropriate new relic agent settings and then run com.priceline.grpc.demo.demo.ClientGrpcRunner and you will see output similar to:

Hello Mike Bazos your trace id is[]

Your Environment

Azul Java 17 (Please see the attached logs which include the same program running with grpc 1.3.x and 1.4.x) grpc_1_4_logs.txt grpc_1_3_logs.txt grpc_new_relic_issue.zip

Yeah @kford-newrelic I am not aware of any workarounds, I didn’t have time to dig deeper into the new relic agent code to see exactly what the problem is.

@mbazos Thank you for the detailed info (and repro) on this issue. Do you currently have a workaround to this issue that you’re using?

@kford-newrelic I am not aware of any workarounds, and I am waiting for resolution on this as well.
