please use the entire issue template.

Unless you fill out the issue template completely including all logs, we can't go ahead and help you.

All three logs requested are very crucial here.

XAMPPRocky commented 4 years ago

@georgehrke Thank you, I've now included them. I didn't initially as most of it is garbage, however I believe I've traced the event that is causing the issue and posted the logs for that event above.

georgehrke commented 4 years ago

Okay, so the server is complaining that you are trying to import an event without occurrences.

This is the event in question:

(I truncated the description).

The event starts on 2019-12-23 3pm New York time. It's recurring weekly on Mondays until 2020-01-06 4:59 UTC (equals 2020-01-05 11:59pm in New York).

So if we expand this recurrence rule manually, we end up with the following occurrences:

  1. 2019-12-23 3pm New York time
  2. 2019-12-30 3pm New York time.

Now let's look at the EXDATEs, which cancel recurrence instances: The event contains two, which match the recurrence-rules above:

EXDATE;TZID=America/New_York:20191230T150000
EXDATE;TZID=America/New_York:20191223T150000

Hence this ics is resulting in exactly zero events when expanding.

For the ICS data discussed in the previous comment, it's the expected behavior that the server rejects an import, because you don't want to store calendar data that doesn't generate any valid events.

What we could probably improve here is the error reporting. Depending on the error, the server will return different messages:
