Issuing 'moveWithOnOff' command for 'genLevelCtrl' cluster fails

[theorlangur]

What happened?

In my HomeAssistant automations I'm issuing move with On/Off command to a group of devices (zigbee group).
It was working before z2m 2.7.2.
The payload was (formatted for convenience):

{"command":
     {
            "cluster":"genLevelCtrl",
            "command":"moveWithOnOff"
            ,"payload":{"movemode":1,"rate":65}
     }
}

Now this doesn't work since new payload parameters were introduced (according to spec, I know): optionsMask and optionsOverride.
z2m was complainting on the absence of those, so I added them with 0s like so:

{"command":
     {
            "cluster":"genLevelCtrl",
            "command":"moveWithOnOff"
            ,"payload":{"movemode":1,"rate":65, "optionsMask":0, "optionsOverride":0}
     }
}

z2m stopped complaining about missing parameters but I'm still getting a

z2m: Invalid message 'undefined', skipping...

and the command is not issued.
I can see in logs that my request is received:

[2026-01-05 19:25:55] debug: 	z2m:mqtt: Received MQTT message on 'zigbee2mqtt/Living Window Lights/set' with data '{"command":{"cluster":"genLevelCtrl","command":"moveWithOnOff","payload":{"movemode":1,"rate":'65', "optionsMask":'0', "optionsOverride":'0'}}}'

I'm not sure what it doesn't like and what can I do about it.
A little help, please?
Also it would be nice if missing parameters in the payload would be provided by the z2m setting them to their respective defaults.

This change of behavior came with commit: 685a781be
from a pull-request:
Koenkk/zigbee-herdsman-converters#10983

What did you expect to happen?

after providing missing optionsMask and optionsOverride I would expect the command to be issued.

How to reproduce it (minimal and precise)

try publishing at a MQTT zigbee2mqtt/<light bulb with genLevelCtrl>/set with the following payload:

{"command":{"cluster":"genLevelCtrl","command":"moveWithOnOff","payload":{"movemode":1,"rate":65, "optionsMask":0, "optionsOverride":0}}}

note: movemode: 0 - up, 1 - down

@Nerivec, as far as I can tell the commit was from you
can you maybe give pointers or maybe you have an idea what might be missing?

[Nerivec]

Can you provide a debug log?

[theorlangur]

log_move_on_off.log

the relevant entry is on line 26 and the error is on line 27
the rest doesn't seem to be relevant (I have 90+ devices in my zigbee network so there's always happening something)

The payload you are sending is not valid JSON.
https://jsonlint.com/
Also be careful when sending text "65" or numbers 65, more often than not the proper type is mandatory.

{"command": {"cluster": "genLevelCtrl","command": "moveWithOnOff","payload": {"movemode": 1,"rate": 65,"optionsMask": 0,"optionsOverride": 0}}}

Sending commands manually is very flexible, but the payload is expected valid in this case.

that has helped
thank you!
