Using topic_filter_regex in carconnectivity.json failed

[Domoberry]

Hello Team,

In the mean time I got Carconnectivty working using Docker on an RPI5. With the WebUI enabled (nice function btw!) I can see many details of the VW ID3. Mosquitto (also on Docker) processes the MQTT output and with an MQTT tool I can subscribe to the CarConnectivity topics. Goal is to update WeConnect-mqtt to Carconnectivity-mqtt for my Domoticz setup. So far so good!
However, I got stuck with using the topic_filter_regex. If I use the example from https://github.com/tillsteinbach/CarConnectivity-plugin-mqtt/blob/main/doc/Config.md:
"topic_filter_regex": "carconnectivity\.0\./garage/WVWAB312[0-9A-Z]+/.*",
a lengthy error is logged via docker logs carconnectivity-mqtt .
Similar, when I use:
"topic_filter_regex": ".*"
If I understood things correctly, ".*" should mean "everything", which I wanted to use to test using the topic filter.
A comparable error results. See attached. I find this error message hard to digest, which would be in line with my 'beginners' experience level :-). CoPilot had some ideas, yet I feel the AI-tool got confused as well.

Question: what should I change to correctly use the topics_filter_regex?

251028 regex error carconnectivity-mqtt.txt
In case addition of the actual carconnectivity.json (as well as docker-compose.yml) would make sense, let me know.
