AWS Database Migration Service requires a role not mentioned in documentation

Question

I am trying to perform a database migration using AWS Database Migration Service (DMS) from a self-managed database on EC2 to AWS RDS. I get this message when I try to run the task to perform the migration.

dms-access-for-tasks IAM Role not configured correctly

The AWS DMS documentation is silent when it comes to a role called dms-access-for-tasks. What policy does it need associating to? Please help.

There seem to be quite a good list of roles and policies needed for DMS at IAM Permissions Needed to Use AWS DMS and IAM Roles to Use With the AWS DMS API - have you got all of that configured correctly? If you still can't make it work post the DMS IAM Role details.

Links are broken. They just go to a generic DMS page with no mention of IAM. – James May 12 '20 at 21:37

The IAM permissions required to use DMS are explained in the AWS documentation pages https://docs.aws.amazon.com/dms/latest/userguide/CHAP_Security.html#CHAP_Security.IAMPermissions and https://docs.aws.amazon.com/dms/latest/userguide/CHAP_Security.html#CHAP_Security.APIRole
