ORA-31528: could not find change set string for CDC subscription string

What triggered the Error:

The change set was missing for an imported Change Data Capture subscription.

What should we do to fix it:

Drop the imported subscription because it is invalid. Verify that the schema containing the missing change set was included in the original export. If needed, perform the export again, including the schema of the missing change set.
