    There's an error in your syntax.
    You don't need this part of config to call for om_kafka module and this is the one which produces the error:

    <Extension kafka>
    Module om_kafka

    Please try to remove it.

    ok it worked! but I still receive this error is it important?
    2021-02-16 14:50:53 WARNING [om_kafka|to_kafka] rdkafka: [thrd:app]: No `bootstrap.servers` configured: client will not be able to connect to Kafka cluster

    This one seems to be an issue on Kafka side as this isn't our internal error, instead it is what NXLog received from.
    This thread from SO could be helpful through I suppose it worth to ask somebody from the corresponding team: https://stackoverflow.com/a/60260899
