Internal Server error

[alst1]

Hi, I’m new in HA, had integrated waste collection for our local service and worked fine.
After upgrading HA core 2025 (?) the complete integration stopped working.
if I will configure it again a message appears: 500 Internal Server Error Server got itself in trouble.
Reload or downgrade didn‘t help.

anyone has same error?

same with me !

when trying to setup a provider:

Unknown error occurred

completely removed and reinstalled integration, several restarts : always the same result ..

Same here. Stopped to work :(

Only found one solution if ICS Cal is installed, downgrade it… but in my setup no IcS is installed…

this will probably be fixed after #3421 or #3468 is merged

TLDR: remove from waste_collection_schedule.service.ICS_v1 import ICS_v1

and

            self._ics = ICS_v1(
                offset=offset,
                split_at=split_at,
                regex=regex,
                title_template=title_template,
            )
