I have defined my GenericMQTTThing in OH UI but when i look at the openhab.log, i get this :
2025-07-10 15:24:28.067 [ERROR] [nal.common.AbstractInvocationHandler] - An error occurred while calling method 'ThingHandler.handleCommand()' on 'org.openhab.binding.mqtt.generic.internal.handler.GenericMQTTThingHandler@6041d430': Topic [tuya/bf6efexxxxxxxxxx/X2A#{aHMEH+|RTwI/192.168.1.235/command] must not contain multi level wildcard (#), found at index 31.

As you can see, the local key == "X2A#{aHMEH+|RTwI" and that seems to break everything. How can this be fixed ?
Many thanks
