Module allsky_publishdata.py failed on MQTT data publication

[PiotrNomad]

Describe the bug When trying to publish data to MQTT broker the module throws the exception in allsky.log: ERROR: Module allsky_publishdata.py failed on line 224 - Client.init() missing 1 required positional argument: 'callback_api_version' Nothing beeing published to MQTT.

To Reproduce Steps to reproduce the behaviour:

1. install BookWorm 32 bit lite on Rasberry pi
2. install Allsky
3. install publishdata module
4. configure MQTT broker
5. Activate publishdata module
6. Restrt Allsky
7. Waith for the 1st picture publication
8. See error in /var/logs/allsky.log

Expected behaviour No error in log data been published

Allsky Information:

• OS: Linux allsky 6.6.20+rpt-rpi-v8 #1 SMP PREEMPT Debian 1:6.6.20-1+rpt1 (2024-03-07) aarch64
• Allsky Version: 2023.05.01_04
• Pi model: Model 4B Revision 1.4 (2 GB)
• Camera: HQ

Additional context It seams thst this is typical behavior on BookWorm Rasbian. I had the same issue with my code and solved it by: client = paho.Client(paho.CallbackAPIVersion.VERSION1)

When I change theline 254 from: client = paho.Client(client_id="", userdata=None, protocol=paho.MQTTv5) to: client = paho.Client(paho.CallbackAPIVersion.VERSION1, client_id="", userdata=None, protocol=paho.MQTTv5) it works :)
