ORA-31530: could not find published column string for CDC subscriber view string

.string

What triggered the Error:

A published column 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 published column was included in the original export. If needed, perform the export again, including the schema of the missing published column.
