[Wilfried278]

I Have A Problem With:

A specific source, The integration in general

What's Your Problem

When starting resp. Adding the integration (UI) and I want to select the provider I get the following message : unknown Error

Source (if relevant)

No response

Logs

No response

Relevant Configuration

No response

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.

What other custom components do you have installed? ics_calendar version 5.0.4? if yes, check here

I have carried out all the steps as described. The error message "unknown error occurred" when selecting many providers that use ICS has remained unchanged.

What is the output of pip list | grep ical and share the error log of home assistant not only the error message.

That works for me - many thanks!
Next step: find a working ics-calendar-version. :)
