Test Script is failing due to trace-collector in Nest JS application

[kpreeti2588]

Hello, I am trying to collect traces from @opentelemetry/exporter-trace-otlp-grpc package in Nest JS application .
Everything is working fine and I am able to collect/view trace in Grafana Stack. But when I am trying to run npm run test command, module test specification script app.module.spec.ts file is giving error. Here is the error:
C:\Finastra\preet\transactions-persistence-worker\node_modules@opentelemetry\exporter-trace-otlp-grpc\build\src\OTLPExporterNodeBase.js:59

I tried with multiple otel collector available for use to collect trace but every collector is giving the error in onInit function
Can anyone suggest some workaround for the same?
