[mqtt.homeassistant] 4.3.1 seems to break zigbee2mqtt light things

[zolakk]

After upgrading from 4.3.0 to 4.3.1 all of my zigbee2mqtt things for lights/bulbs (various brands) come online but have no channels or show HANDLER_INITIALIZING_ERROR Cannot invoke "String.isBlank()" because "result" is null. Removing and re-adding seems to have the same result. Reverting to 4.3.0, everything works as expected again. Tried a fresh install of 4.3.1 to test with same results (broken in 4.3.1, working in 4.3.0). Also have an Inovelli zigbee fan module that is showing the same behavior, possibly because it has a light channel?

Have zigbee sensors and buttons that all seem to work fine on 4.3.1 so far.

Expected Behavior

all zigbee things come online, populate the proper channels, and work

Current Behavior

zigbee2mqtt light things either don't populate channels or show HANDLER_INITIALIZING_ERROR
Cannot invoke "String.isBlank()" because "result" is null.

Log file shows this when getting the String.isBlank(), nothing showing when no channels:

Noticed #18021 after posting, built the latest binding from source and it seems to be working as expected now so closing this one

I updated and facing the same problem.
How do I fix it now without waiting for 4.3.2 ?!
