RhodeCode CE/EE

After updating from 4.11.5 to 4.12.2, our webhook integrations seem to be failing somewhere before RhodeCode actually makes the web request.

I couldn't find anything in any of the log files explaining what was happening, but the rhodecode_celery.log file indicated that the webhooks were going through celery. I was able to get the following error log by running profile/bin/celery events --app rhodecode.lib.celerylib.loader --ini ./rhodecode.ini -d from the ~/.rccontrol/enterprise-1 directory while triggering a webhook (sensitive details have been edited):
