Thanks for reporting! This is an issue in the upstream ics-filter module. I've created a PR to fix this.

[KristjanESPERANTO]

@dwburger The PR got merged and a new ics-filter version was released. So this issue will be official fixed in the next MagicMirror release.

You can already check it out if you run npm update ics-filter && git restore package-lock.json in your MagicMirror directory. Feedback would be nice :)

Hi, Kristjan, I'm glad the bug report was useful, and it helped make the Magic Mirror better. I'm a beginner user of the MM and a beginner with Javascript programming. I relied on ChatGPT to help with the bug fix on my MM and to write the bug report. Right now, my calendar module is working so I'm not inclined to check out the new code as you suggested. However, when a new release of the MM is available I'm sure I'll give that a try. Best wishes!
