IAM Error while using ecs-cli

Question

I'm trying to create a new Task for ECS using a compose file, but i'm getting an AccessDeniedException even when my user has the required permissions.

$ ecs-cli compose --project-name test create

The user have this policy attached:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "ecs:RegisterTaskDefinition",
                "ecs:ListTaskDefinitions",
                "ecs:DescribeTaskDefinition"
            ],
            "Resource": [
                "*"
            ]
        }
    ]
}

I also tried attaching the AmazonEC2ContainerServiceFullAccess (that have ecs:*), but didn't work.

Found the problem, the user i was using had a policy to use MFA (MultiFactor Auth), that is not supported by the ecs-cli.
