Object detection working, kind of

I'm running 1.33.12 on Raspian Buster - I've tried upgrading to 1.33.14 but it's dependencies break other things I have installed. Anyway, I've got object detection working in that the logs show it detecting the object(s) (car, person etc) but then it throws "Could not write image to ZoneMinder as eventpath not present". I've double checked that write_image_to_zm=yes and hook_pass_image_path=yes. I've got wait: 10 in my ini file, and this is happening both in real-time detection and when running detect_wrapper from the command line. Any ideas as to what might be throwing the "eventpath not present" error??

I managed to get up to 1.33.14 and the same thing happens - I've tried grabbing zmeventnotification from GIT and reinstalling with new .ini files, same result.

As you might have already seen, the
comments just above the setting say you need 1.33.x. Now that you have updated to 1.33.x, this should not happen. Please post debug logs.
You'll know you are on the right ZM version, when you do the following test:
1. Launch a browser, login to ZM
2. Launch another tab and type in
Code: Select all
https://yoursever/zm/api/events.json
In the output, if you see a field called "
FileSystemPath" for event entries, you are good.
example:
Code: Select all
{"Event":{"Id":"12344","MonitorId":"10","StorageId":"1","SecondaryStorageId":"0","Name":"New Event","Cause":"Continuous","StartTime":"2019-07-14 12:25:15","EndTime":null,"Width":"1280","Height":"720","Length":"1300.83","Frames":"7800","AlarmFrames":"0","DefaultVideo":"","SaveJPEGs":"0","TotScore":"0","AvgScore":"0","MaxScore":"0","Archived":"0","Videoed":"1","Uploaded":"0","Emailed":"0","Messaged":"0","Executed":"0","Notes":"","StateId":"1","Orientation":"0","DiskSpace":null,"Scheme":"Medium","Locked":false,"MaxScoreFrameId":"833061","FileSystemPath":"\/var\/cache\/zoneminder\/events\/10\/2019-07-14\/12344"}}

Hi
I'm facing a seemingly similar issue. Zoneminder is version 1.33.16.
Test from command line:

Images are pulled and debug image written:
Code: Select all

FileSystemPath seems to be present in event.json:
Code: Select all
FileSystemPath "/zoneminder//4/2020-01-10/1"
Suggestions? I can't load the events.json directly with curl but it loads in firefox, might that be it?
Thanks,
Torkil

What is the exact command line instruction you are using?

You also need to pass the event path if you want to test the event path functionality. Or just run it as a daemon and when an event is detected it will work.
