What version of Traccar are you using?
Traccar Manager 5.1.1
Traccar Server 6.7.2
I just noticed Traccar Server 6.7.3 is out at Traccar Download page. I will update it shortly. Thanks Anton.
Updated toTraccar Server 6.7.3 now and monitoring, hope the error will go away.
At the moment of monitoring. No error pop up yet.
If it doesn't, let me know what the steps to reproduce the issue are.
Bad ... Problem still persist after upgrading both server plus manager and client to all latest version.
You need to provide more details on what leads to this problem.
Let me troubleshoot further. Sorry ya. I need to see what would have triggered this.
Maybe my colleague removed some linked geofence profile he deleted off before unlinking it from a device profile.
Before this action there where no such issue. I guess the database must have got old data values not removed as the result of him removing serveral linked geofence.
I will reverr once gather some information. Thanks Anton.
I notice each time a tracker enter a geofence it will trigger alert geofence entered follow by geofence exited. This result in error red box ... Cannot read properties of undefined (reading eventld") ... I guess this issue related to Traccar Server thread group ... I notice this error happened since server version 6.7.0.
Just to update the error "Cannot read properties of undefined (reading eventld")" popup at every event notification trigger at Traccar Manager app user interface.
Found the problem. A fix is coming soon in a new version of Traccar Manager.
Wow you are the greatest! Many thanks for your motivation and deligance on support. Yup error has gone away on Traccar Manager version 5.1.2. Love you Anton.
