<Your answer>

What is the captured database version and mode of deployment?

(E.g. on-premises, with a specific cloud provider, etc.)

on-premise with Kafka connect

What behavior do you expect?

Debezium UI should work properly.

What behavior do you see?

Debezium UI says "Something went wrong" in "Essential connector metrics". See screenshot

In the browser network tab I see it is trying to reach
<kafka-connect-instance>/debezium/mysql/connectors/connector-meloncrisp2/metrics

It should not be trying to use mysql. because I am using postgres.

I see in the code that it is "mysql" is hardcoded in ConnectorDetails.tsx.

If I change that to "postgres" then the UI works.

Do you see the same behaviour using the latest released Debezium version?

yes

Do you have the connector logs, ideally from start till finish?

yes
