When I send the code 'ActiveTrackOperator.startTracking' I always get the error: 'Execution of this process has timed out', almost immediately, not even one second later. Do you know what I can do to stop it?

Drone: Mavic Air

This feature is being implemented long time ago and hasn't been update for a long time. This means it might not work with some new drone models. But maybe you are using it wrong. You must make sure the target you want to track is very obvious comparing to the background. Because in fact, the activeTracking is using graphic algorithm. Try our demo and see what happened.

In my experience, that tutorial works correctly in MavicPro.
However, newer models such as Mavic2Pro, Mavic2Zoom, etc. will show a timeout error.

We've already reported this to DJI and are waiting for their response.
