help request: opentelemetry plugin with grpc server upstream can't send trace

[bai-ming]

Description

I create a route for grpc server,
the config like this

I can get the correct response but the trace send failed.

At first, I deleted the grpc-translate plugin but the trace still send failed

Next, I change a new upstream with the scheme is HTTP.

At this time, the trace send successfully.
So I wonder if there is something wrong between opentelemetry plugin and grpc server? Or I have some problems with my configuration?
