`Failed to delete stack: Role <role> is invalid or cannot be assumed` Assume this role from the cli if your cloudformation stack can't delete

Create a role with a trust policy that can be assumed by Cloudformation. Trust policy looks like this:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "",
 "Effect": "Allow",
