Cannot connect Google Ical to oncall

[yasharne]

What went wrong?

What happened: When I try to add a Google Ical link, I get the below error:

Ical URL primary: Ical parse failed

I checked the code and realized grafana oncall inside the fetch_ical_file function is expecting text/calendar but in the oncall logs I see the response code is still text/html:

grafana-oncall-engine-1  | 2023-09-11 11:43:23 source=engine:app google_trace_id=none logger=apps.schedules.ical_utils fetch_ical_file: content-type=text/html; charset=utf-8

Hi,

To be sure, are you using the secret iCal URL from Google Calendar? Otherwise your calendar needs to be public for OnCall to be able to import it [1].

Hi @matiasb Yes, we are using the address which is inside the Public address in iCal format

Please use private link

Note: Use the secret iCal URL to avoid making the calendar public. If you use the public iCal URL, the calendar and event details must be public for Grafana OnCall to read your calendar.
