Trying update from 1.9.7 to 2.3

 database.history.file.filename = data/db-history.dat
 database.user = xxx_production
 transforms.singleTopic.topic.regex = ([^.]+).*
 transforms = singleTopic
 database.server.name = debezium_mysql_xxxxx
 transforms.singleTopic.type = io.debezium.transforms.ByLogicalTableRouter
 transforms.singleTopic.topic.replacement = $1

What is the captured database version and mode of depoyment?

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

Kubernetes deployment in GKE cluster

What behaviour do you expect?

Successful update

What behaviour do you see?

Failed with error about topic.prefix (need it)

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

(Ideally, also verify with latest Alpha/Beta/CR version)

Trying to update to the latest

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

(You might be asked later to provide DEBUG/TRACE level log)

Right now don't have, as rollback to old version
