fix: handle possible date field lookup exceptions

[gabek]

This adds a simple try/catch around parsing the date lookup key to catch exceptions, and allow the script to continue.

Hopefully addresses #61. Though I'm not sure how to test a dev version of a Obsidian plugin, so I'm being naughty and pushing up untested code.

Hi there @muness! What do you think about catching these exceptions when parsing calendar items?

[muness]

Hi @gabek , I like it but I'd prefer it if it wasn't silent, maybe a toast notification with the number of issues across number of calendars and a bit more info in the console.

Added error handling in #73 that includes a note to the user.

@gabek , please give 1.2.1 a try and let me know if that captures the error. Thanks! https://github.com/muness/obsidian-ics/releases/tag/1.2.1

No luck parsing, but at least it's caught and there's an error pointing to something:

plugin:ics:21 Error filtering events for calendar Personal: RangeError: Invalid time value

I'm not sure if it's helpful, but here's an example event that I randomly took from my calendar.

DTEND;TZID=America/Los_Angeles:20230911T210000 to my eyes looks like the issue. I think the timezone is usually at the end, like DTEND;20230911T210000Z-0700

Do you have the exception stack handy? I am curious as to where this is failing: my code or something in node-ical or rrule

[gabek]

Sure!
