I created a DMS instance in a public subnet without public access. Kafka is created as an MSK cluster in a private subnet, within the same VPC. No SSL.

Endpoint testing shows application error 1020912: failed to connect to database.

I can confirm that Kafka is running fine, and I can list topics via a bastion host in the same subnet as the DMS instance.

It seems that the console and docs are misleading stating that topic is optional. The topic is compulsory and must exist when testing the connection.

Adding auto.create.topics.enable = true does not work for testing connections.
