Rel. 6.0

I installed Rel 6.0 but tracking doesnt work. In Log there is a message

2024-04-07 00:25:02  INFO: [T588be9a4] error - Cannot invoke "org.traccar.model.Position.getDeviceId()" because "position" is null - NullPointerException (PositionUtil:40 < PostProcessHandler:50 < ProcessingHandler:179 < ...)

Looks like it's related to filtering.

I didnt change anything. 5.12 work fine.

I checked it again with 5.12 and 6. Rel 6 is fault.

I'm not saying that you changed something. I'm just saying that it's related to filtering. Try the preview:

seems to work
