How to initialise a zigbee controller properly?

Raspberry-Pi

I'm working with a RaspBee Hat for Raspberry Pi, made by Dresden Electronik.

For this project (NodeJS) I use the Deconz-api I found here:
GitHub - mozilla-iot/deconz-api at improvements[^]

When I run my code to enumerate all devices known to the controller, it hangs on the first run. Then, it always return an empty list on consecutive runs.

If I first start the application that came with the RaspBee Hat (Deconz), then close it and rerun my code, everything works fine, and my code returns everything I ask for.

This make me suspect that I have to do some initialization of the controller before I ask for known end devices.

I am aware that this question is pretty abstract, but are there any takers ot there?

What do I have to do to a ZigBee controller device before I start enumeration network devices?

This is a NodeJS project.

TIA...

I'm running the discover.js in the /examples folder from the github repository linked above.
