Backup job failed because of insufficient privileges.

I created user with full admin access and then i used that user creds to run terraform code to create backup vault/plan and create role to run it .

However , if i create backup using the new role created from terraform backup fails with above error. However , if i create backup of same server using role i created manually in GUI seems to work. both roles have correct perms as following: arn:aws:iam::aws:policy/service-role/AWSBackupServiceRolePolicyForBackup arn:aws:iam::aws:policy/service-role/AWSBackupServiceRolePolicyForRestores
