What Debezium connector do you use and what version?
I am using Informix Debezium Connector and the version of the jars is 2.6.1 Final.
What is the connector configuration?

What is the captured database version and mode of depoyment?
I am using the below versions of Informix and I am using the KAFKA Connect UI for Debezium connector deployment.
Informix Dynamic Server
14.10.FC10W1X2
Informix JDBC Driver for Informix Dynamic Server
4.50.JC10
KAFKA Version: 7.4.1-ce
What behaviour do you expect?
After setting up the required configuration to exclude a column (i.e., "column.exclude.list": "mcp.kafkatable.value1") in the Informix source connector, the expectation was that CDC would be enabled for the table "kafkatable". Once an insert is executed on this table, CDC would capture the activity, save the table schema in the schema registry, and publish a message in the topic by the connector.
What behaviour do you see?
After setting up the required configuration to exclude a column (i.e., "column.exclude.list": "mcp.kafkatable.value1") in the Informix source connector, an insert was executed on table kafkatable. In the KAFKA Connect logs, it was being logged that the internal schema is out of sync with the real database schema, however, kafkatable was a new table on which CDC has not been enabled before, and thus there was no schema of this table in the schema registry.
Do you have the connector logs, ideally from start till finish?
