Zigbee works, but not zigbee2mqtt (whats herdsman?)

I am rather new on using HA, so please excuse me if this is explained elsewhere.
I did search first, though.

I have been using zigbee automation since the autumn, and it works nicely, but I have not been able to start zigbee2mqtt, it seems.

Here is a log :

Please assist? Should I create a new installation?
I’m closing in on that step, but it’s a bit of work since I have quite a few devices…

I do appreciate the openness of the HA code and architecture, but the threshold to get everything to work is not zero…

You just updated to v2.02 without reading the release notes. No need to reinstall anything. There are just some config changes you must make as detailed here: Zigbee2MQTT 2.0.0 breaking changes · Koenkk/zigbee2mqtt · Discussion #24198 · GitHub
