I have set up an alert using webhooks and they have not been firing.
I have set the notification to also show up in triggered alerts to make sure that the alert was in fact firing. When looking through the logs via index=_* webhook action=webhook I found some errors, which I cannot figure out how to remediate:
event_message: action=webhook - Alert action script returned error code=3 event_message: action=webhook - Alert action script completed in duration=64 ms with exit code=3 event_message: action=webhook STDERR - Unexpected error: POST data should be bytes, an iterable of bytes, or a file object. It cannot be of type str.
