Misleading error message on waiting for task to start if the runner doesn't have permissions ecs:DescribeTasks

[mmuarc]

Hello,

I've been banging my head against the wall for a while because of this issue.

If the runner doesn't have ecs:DescribeTasks permissions, the action errors out with a timeout on the Start timer.

I suppose it's because the waiter is intended to hide exceptions so that if it can't reach to check for the state it simply keeps trying until the timeout happens. The error message you get is: Task did not start successfully. Error: {"state":"TIMEOUT","reason":"Waiter has timed out"}. even when the task runs nicely and finishes.

I checked the code and saw you are using a command by the aws sdk. So digging a bit I figured this could be the issue.

In case you can't do much to fix this on your side, it would be great for the next person if you could add this behavior to the documentation.

Thank you very much for your work!
