Zigbee Null Error

Hi, I’m trying to pair my Yale YRD-220 ZigBee lock with V2 UK hub, the lock says successful while the hub can’t see anything… tried adding a new device manually using the zigbee id from the events list, but there’s no response from the lock… I keep getting this error in the live log upon pressing lock/unlock: java.lang.IllegalArgumentException: Needs to be string or int, received null value: null

I’m using this DTH: Universal Enhanced ZigBee Lock

Any idea what I’m missing?
