opentelemetry with grpc exporter

[BabakScript]

Hi,

I wanted to integrate @envelop/opentelemetry with @opentelemetry/exporter-trace-otlp-grpc package inside my graphql-mesh project. I did it like this:

import { execute, parse, specifiedRules, subscribe, validate } from "graphql";
import { useOpenTelemetry } from "@envelop/opentelemetry";
import { useEngine } from "@envelop/core";
import { Resource } from "@opentelemetry/resources";
import { SemanticResourceAttributes } from "@opentelemetry/semantic-conventions";
import {
  BasicTracerProvider,
  SimpleSpanProcessor,
} from "@opentelemetry/sdk-trace-base";
import { OTLPTraceExporter } from "@opentelemetry/exporter-trace-otlp-grpc";

import env from "../../env";

const provider = new BasicTracerProvider({
  resource: new Resource({
    [SemanticResourceAttributes.SERVICE_NAME]: env.OTLP_EXPORTER_SERVICE_NAME,
    [SemanticResourceAttributes.SERVICE_VERSION]: "1.0",
    [SemanticResourceAttributes.DEPLOYMENT_ENVIRONMENT]: "development",
  }),
});
const exporter = new OTLPTraceExporter({
  url: env.OTLP_EXPORTER_ENDPOINT,
  headers: {
    Authorization: env.OTLP_EXPORTER_Authorization,
  },
});

provider.addSpanProcessor(new SimpleSpanProcessor(exporter));
provider.register();

const envelopPlugins = async () => {
  return [
    ...(env.ENABLE_OPEN_TELEMETRY
      ? [
          useEngine({ parse, validate, specifiedRules, execute, subscribe }),
          useOpenTelemetry(
            {
              resolvers: true, // Tracks resolvers calls, and tracks resolvers thrown errors
              variables: true, // Includes the operation variables values as part of the metadata collected
              result: false, // Includes execution result object as part of the metadata collected
            },
            provider,
          ),
        ]
      : []),
  ];
};

export default envelopPlugins;

I'm getting no error. Nothing but I also don't get any trace info. Did I miss anything? 🤔
