Additional context

I am using manual instrumentation through an interceptor in our common interfaces for Services, Repositories, Controllers, etc...

Previously i was using Jaeger exporter to view my traces in Jaeger UI. However since that package is deprecated i am trying to switch to the OTLP exporter at this moment.

Current workaround is to switch back to the deprecated Jaeger exporter for now.
