I am trying to instrument a metric data to kafka via otel in json format. But the data is written in otlp format in kafka topic. Any inputs please?
receivers:
      otlp:
        protocols:
          grpc:
          http:
exporters:
  logging:
  kafka/metrics:
    protocol_version: 2.0.0
    topic: otlp.metrics
    brokers:
      - localhost:9092
    encoding: otlp_proto

connectors:
  spanmetrics:

service:
  pipelines:
    metrics:
      receivers: [otlp, http]
      processors: [filter, batch]
      exporters: [kafka/metrics]

change the encoding? `encoding: otlp_json`
