Sink AVRO messages from pulsar topic to elasticsearch

Question

It is possible to sink messages from pulsar topic which uses avro schema? Im try to use this solution:

https://pulsar.apache.org/docs/next/io-elasticsearch-sink/

But my problem is if i want to use the connector with the option "schemaEnable : true" then i get the follow error

Uncaught exception in Java Instance
java.lang.UnsupportedOperationException: **Unknown AVRO schema type=ENUM**

Do we need a custom sink connector in this case?

Thank you very much!
