I have set up debezium with topic routing enabled.
After adding a new table to connector configuration I've received the following error:

The reason for the issue is that the new table doesn't have a primary key and topic routing is enabled. So, debezium tries to add an original topic name to message key, but message key is `null` (because the table has no primary key).
Is there any way to use topic routing with a table without a primary key?
