How to fix permission error of Ebs volume using Amazon Data lifecycle manager?

Question

I applied the terraform code in this link, which contains code to apply the specific roles and permission s to service dlm lifecycle for ebs volumes.

But still I am getting access errors.

Please share any suggestions on how to fix this.

Few more steps I tried. With policy actions set to all ec2 permissions ("ec2:*"), snapshots are created without error.

But if I tried below permissions, which I got from default policy created when attempted to create lifecycle from webconsole.

{
            "Effect": "Allow",
            "Action": [
                "ec2:CreateSnapshot",
                "ec2:CreateSnapshots",
                "ec2:DeleteSnapshot",
                "ec2:DescribeInstances",
                "ec2:DescribeVolumes",
                "ec2:DescribeSnapshots",
                "ec2:EnableFastSnapshotRestores",
                "ec2:DescribeFastSnapshotRestores",
                "ec2:DisableFastSnapshotRestores",
                "ec2:CopySnapshot",
                "ec2:ModifySnapshotAttribute",
                "ec2:DescribeSnapshotAttribute",
                "ec2:DescribeSnapshotTierStatus",
                "ec2:ModifySnapshotTier"
            ],
            "Resource": "*"
        }

With above permissions, it is not working. Any suggestions
