I am trying to Migrate my Postgresql RDS to Aurora Postgresql using DMS.

All my tasks are failing, and I am unable to understand what can be done to help the tasks progress.

The error from cloud watch logs is

I have checked the Postgresql Roles, Privileges and even disabled triggers using the SET session_replication_role = 'replica';.

I am at my wits end as to why this is failing and how to rectify it.

I am migrating from RDS Postgres 9.5.16 to Aurora Postgres 10.7

Any help is appreciated. Thanks
