Modifying tsconfig.json

To make TypeScript recognize the Opentelemetry Plugin, you need to add an alias in your tsconfig.json.

    }
  }

      cluster: '{env.OPENTELEMETRY_CLUSTER}'
      serviceName: '{env.OPENTELEMETRY_SERVICE_NAME}'
      serviceNamespace: '{env.OPENTELEMETRY_SERVICE_NAMESPACE}'
      delegationArgs: true
      traceIdInResult: '{env.OPENTELEMETRY_TRACE_IN_RESULT}'
