ServiceNow Sink Connector Serialization Issue


I’m new to Confluent cloud, trying to setup the connector “ServiceNow Sink Connector” on confluent cloud.
I hope I can produce a message on confluent cloud directly and want the connector to read this message and update one incident record on a ServiceNow instance.

However, when I tested this connector, I saw a serialization issue, I pasted part of the error as below:

“key”: “__connect.errors.exception.message”,
“value”: "Converting byte to Kafka Connect data failed due to serialization error of topic incident_sink: "

I investigated and realized that I might need to configure schema registry first, however, I did not find any useful document about how to configure it on cloud confluent, so I created this topic, it will be appreciated if anyone can provide some help, thanks in advance!
