Kafka connect failed with OCI Stream service


Im trying to setup Kafka connect with OCI Stream Service.

Below is Kafka connect docker configuration,

  connect:
    image: confluentinc/cp-kafka-connect-base:7.0.0
    hostname: connect
    ports:
      - 8083:8083
    container_name: connect
    environment:
      CONNECT_BOOTSTRAP_SERVERS: '<BOOTSTRAP_SERVER>'
      CONNECT_REST_ADVERTISED_HOST_NAME: connect
      CONNECT_REST_PORT: 8083
      CONNECT_GROUP_ID: compose-connect-group
      CONNECT_CONFIG_STORAGE_TOPIC: '<KAFKA_CONNECT_OCI_ID>'-config
      CONNECT_CONFIG_STORAGE_REPLICATION_FACTOR: 3

      CONNECT_INTERNAL_VALUE_CONVERTER: "org.apache.kafka.connect.json.JsonConverter"
      CONNECT_LOG4J_ROOT_LOGLEVEL: "INFO"

      CONNECT_CONSUMER_MAX_POLL_RECORDS: 1000
      KAFKA_HEAP_OPTS: "-Xms1G -Xmx4G"    

Getting below error

ERROR [Worker clientId=connect-1, groupId=compose-connect-group] Uncaught exception in herder work thread, exiting:  (org.apache.kafka.connect.runtime.distributed.DistributedHerder) org.apache.kafka.common.errors.TimeoutException: Timeout of 60000ms expired before the position for partition <KAFKA_CONNECT_OCI_ID>-offset-0 could be determined
INFO Kafka Connect stopping (org.apache.kafka.connect.runtime.Connect)

I don't think there are network issues, Because when I have different topic name or wrong bootstrap server then I get different error, not even starts up. But for me this error gets after a min, mean time REST calls for GET requests work.

Please note that similar config for AWS MSK works for me.

Please help me to resolve the issue.

UPDATE: OCI streaming service doesn't support latest version of Kafka connect. It worked after I changed to 5.x
