"Webhook previously received, aborting."

I’m getting a Webhook previously received, aborting. when running a GitHub webhook for a template , I suspect coming from here:

https://github.com/ansible/awx/blob/eec4f8dcc27428cd1aeb1c251d43052a3ea780e8/awx/api/views/webhooks.py#L130

The AWX gui does not show any jobs being queued/waiting/running, how can I clear this error to allow my webhooks to return to normal? We’ve had this template running through webhooks without any issues, before.

version 17.0.1.
