Bug

Details

zm_detect.py fails to write an image when an object is detected. The error that is produced points towards polygons=matched_data['polygons'] in the main_handler. I am able to fix the issue by changing matched_data['polygons'] to g.polygons, but I am unsure if this is the right way to do it. I am not going to post the entire output of --debug unless it will help with this issue.

Run script:

root@zoneminder-574b887558-zfk2j:/# sudo -u www-data /var/lib/zmeventnotification/bin/zm_detect.py --config /etc/zm/objectconfig.ini --eventid 319 --monitorid 2

You need to update pyzm and ES/hooks

Thanks, I will try that! I am using dlandon's docker image, and I started running into some problems with a recent update, my configs were a mish-mash of old and new, so I'm trying to get everything sorted out.
