HASS MQTT Cat Flap is not controllable, changing the switch results in frontend.py Error

[Pr0mises]

Firstly, awesome project and beautiful documentation. I didn't even need to change my Firmware as my Hub is using 2.43 (thankfully, I disabled the force updates on it).

Background information about my system:
RaspberryPi 4:

• eclipse MQTT broker as docker container
• HASS as docker
• PHL as docker

Setup run fine and my HUB + Cat Flap got published into MQTT in HASS just fine as well.

In my cat flap I've 3 options as switches Curfew KeepInand KeepOut. All three aren't enabled yet by default.
I tried to hit any of those switches and got this error in PHL:

After pressing any Switch:

I cleaned the log.
In the MQTT logs I get this:

1679968001: New connection from <IP>:54926 on port 1883.
1679968001: New client connected from <IP>:54926 as PetHubLocal (<cleared, not sure if needed>).

I'm kinda lost, and I've no clue where to debug, as it seems to work for you guys.
Maybe someone can help me with that or at least point me in a direction if it's my MQTT Broker or PHL.

Thank you

I did some more testing and it turned out that
await sio.emit('web_message', data=parsed_result, broadcast=True, include_self=False) (frontend.py#L345)

needs to be replaced to

await sio.emit('web_message', data=parsed_result)

now everything is working as expected
