Observed Behavior

Incorrect Usage: flag provided but not defined: -endpoint

NAME:
   ecs-cli local create - Creates a Compose file from an ECS task definition.

USAGE:
   ecs-cli local create [command options] [arguments...]

OPTIONS:
   --task-def-file value, -f value    Specifies the filename value that contains the task definition JSON to convert to a Docker Compose file. If one is not specified, the ECS CLI will look for task-definition.json.
   --task-def-remote value, -t value  Specifies the full Amazon Resource Name (ARN) or family:revision value of the task definition to convert to a Docker Compose file. If you specify a task definition family without a revision, the latest revision is used.
   --output value, -o value           Specifies the local filename value to write the Docker Compose file to. If one is not specified, the default is docker-compose.ecs-local.yml.
   --force                            Overwrite output docker compose file if it exists. Default compose file is docker-compose.ecs-local.yml.
   --use-role                         Uses the task role ARN instead of temporary credentials.
