Custom Integration Bosch SHC throwing errors about invalid poll id

I get warnings in my log files at irregular intervals. They say:

Logger: boschshcpy
Source: /usr/local/lib/python3.12/site-packages/boschshcpy/session.py:151 
---
SHC claims unknown poll id. Invalidating poll id and trying resubscribe next time...

Does anyone have any ideas where they come from and what to do about them?
