Debezium heartbeat table not updating - postgresql

Question

There is already a question Debezium Heartbeat Action not firing but it did not resolve my issue.
Here is my source connector config for postgres. It is generating heatbeat events after every 5 seconds. I have confirmed that by checking kafka topic but the issue is that it is not updating the row in the database heartbeat table. Any suggestions?

} }

Try to share your heartbeat table with a DDL. Your heartbeat table have a primary key? Debezium only track updates and deletes if table have PK defined. Also try to share your debezium version because this propertiers change from version to version.
Try a UPDATE without WHERE to test if the problem is in your query. Check if your heartbeat in your schema public or inventory and add as a prefix in your query.
UPDATE inventory.heartbeat SET ts = NOW();
On your tables.include add for each table a prefix with schema.
"tables.include": "inventory.customers,inventory.heartbeat",
On tables.include try to change to tables.include.list. Source: https://debezium.io/documentation/reference/1.6/connectors/mysql.html#:~:text=connector%20configuration%20property.-,table.include.list,-empty%20string
"tables.include.list": "inventory.customers,inventory.heartbeat",
