I’m in the middle of trying to set up an autoscalinggroup for an existing ecs cluster. It was having issues with something being in ROLLBACK_COMPLETE state so I did a refresh, but now I get a
panic: fatal: An assertion failed
error. I will post the stack trace in a thread reply

This is failing because the id of the resource being `get`d is empty. We should be failing with a better error here. is related - could you share details of your case there?

@white-balloon-205 I can, though I don’t have much details. Although now all my operations are timing out… 😐
