Devices not loading on map

Hi Anton,
Did some searches but could't find any issue related to this. Admin account (has over 100 devices) loads map ok but does not load the devices on the map. Other accounts with less devices does not have this problem. Browser console shows errors below related to ol-debug.js

Any clue as to what could be going on?

I suspect there is a problem with some device(s). The coordinates might be out of valid range.

Thanks for the response Anton. The coordinates are ok since the same devices load correctly under a different account with less devices attached.

Hi Anton,
I removed some of the devices from this account and the problem goes away (everything loads on the map). Have you tested or noticed this limitation before? i.e do you have a setup that displays multiples devices on the same map and what is the max you have displayed on a map?

Hi Anton,
You were correct. It was just one device that was corrupting the display of all the other devices; it had incorrect data reported. Removing it and everything is back to normal now. Thanks for the help.

Regards,

I have the same problem, however I don't know how to identify which device is causing the error. Is it possible to identify?

You can check the API response. Or maybe use route report.
