[Bug]: C-Trace: Calendar entity not available anymore

[PyHae]

I Have A Problem With:

The integration in general

What's Your Problem

Hi guys,

I'm using WCS for a while. Since yesterday I do not get any infomatiion any more. Calendar tab is empty!

• When I click into the entity management I get the information that calendar.c-Trace ist not provided anymore from "wast_collection_schedule"-Integration
• When I click the 'configuration' button I get the message: 500 Internal Server Error Server got itself in trouble
• When I try to add the calendar ('Germany' / 'Stadt Bayreuth (c_trace_de)' again or any other calendar I get: 'unknown error occured'

Would be great if you could help

Relevant Configuration

Checklist Source Error

• Use the example parameters for your source (often available in the documentation) (don't forget to restart Home Assistant after changing the configuration)
• Checked that the website of your service provider is still working
• Tested my attributes on the service provider website (if possible)
• I have tested with the latest version of the integration (master) (for HACS in the 3 dot menu of the integration click on "Redownload" and choose master as version)

Checklist Sensor Error

• Checked in the Home Assistant Calendar tab if the event names match the types names (if types argument is used)

Required

• I have searched past (closed AND opened) issues to see if this bug has already been reported, and it hasn't been.
• I understand that people give their precious time for free, and thus I've done my very best to make this problem as easy as possible to investigate.

Configuration:
HA 2025.1.2

My integration just started doing this today as well (it was working yesterday).

It looks like my issue was slightly different and updating icalevents to 0.2.0 according to #3488 fixed it.
