Configuration
module: "calendar",
header: "Facebook události",
position: "top_left",
disabled: false,
config: {
calendars: [
{
symbol: "calendar-check",
url: "https://www.facebook.com/events/ical/upcoming/?uid=******&key=******" }
Steps to reproduce the issue:
When I configure url for facebook events calendar, I am constantly getting error:
[2025-09-30 10:37:07.080] [ERROR] Calendar Error. Could not fetch calendar: https://www.facebook.com/events/ical/upcoming/?uid=******&key=****** Error: Bad Request

What did you expect to happen?
I tried to open url in web browser to confirm if it works and it started to download the .ics file which was populated with events, so there is no issue with the url. I have also tried as work around to download .ics file with curl and configure path to this file as url, but this is not supported. I have also noticed that curl only works with parameter -L so it follows redirects.
What actually happened?
