Unable to send service name on NewRelic via opentelemetry-collector

[Anshul0311]

I want to send telemetry data to NewRelic via otel-collector . I am able to see traces via trace.id but not via service.name

I am using below references
Reference:1 For sending data to otel-collector hosted on port 4317
https://github.com/open-telemetry/opentelemetry-rust/tree/main/opentelemetry-otlp/examples/basic-otlp
I can see service.name in the logs getting printed under Resource Attributes section just like this in my otel-collector container. But this service name , I am not able to send to NewRelic

Also, when I was doing POC with jaegar , service name was visible on Jaegar but not visible on NewRelic
