Hello,
I'm running some Kafka load test using xk6-kafka and i'm getting some errors when serializing objects. In my Avro schema there is some fields that are array type and seems that when calling schemaRegistry.serialize() i'm getting the following error:

I tried with another Avro schema without that type array and it worked.
Is there a way to pass that data to the serialice method?
Thanks in advance.
