AWS DMS Migration task from source MongoDB and target RDS Postgres

My multiple migration tasks were successfully running for few weeks then for one of the collection/table I had to include more columns so, I reloaded the table again by adding more rules to the transformation rules, But now the task is failing and premigration task also fails saying. Couldn’t fetch the table definition for table ******* in schema prod__v5_schema

All the connections were working and now also many tables are replicating but for one table showing this error.
