I am trying to setup loki exporter with open telemetry on k8s to push logs to Grafana cloud. But the collector pod itself is failing with “CrashLoopBackOff” error and exit code 1:

"Back-off restarting failed container opentelemetry-collector in pod otelcollect-opentelemetry-collector-agent-lwcz4_otel-demo(9ca4db3b-351b-4033-a156-c64ef5a47a97)"

Below is the configuration used:

  exporters:
    debug:
      verbosity: detailed
    loki:
      endpoint: "https://cloudlogs.grafana.net/loki/api/v1/push"
      auth:
        authenticator: basicauth/logs
  extensions:
    health_check:
      endpoint: ${env:MY_POD_IP}:13133
    memory_ballast: {}
    basicauth/logs:
      client_auth:
        username: username
        password: "generatedtoken"
  processors:
    batch:
      send_batch_size: 10000
  receivers:
    otlp:
      protocols:
        grpc:
          endpoint: ${env:MY_POD_IP}:4319
        http:
          endpoint: ${env:MY_POD_IP}:4320
          logs_url_path: /v2/logs
          traces_url_path: /v2/traces
  service:
    extensions: [health_check, memory_ballast, basicauth/logs]
    pipelines:
      logs:
        exporters: [debug, loki]
        processors: [batch]
        receivers: [otlp]

The container however runs if I revert the loki configurations.
