If I'm using a sensor to implement a run request. As part of that sensor I'm reading from an AWS sqs queue and initiating the run request if a certain message status is received. Is there a suggested way to retry a run if the run initiated from the sensor fails? I'm assigning a run_key to the RunRequest, but even though the run fails I get a response that says a run for this key has already been completed. I'd like to rerun the job with the assigned key if it failed, but skip if it succeeded.
