"Invalid recurrence rule" on some ICS files

I am importing ICS files via a bash script into my GCalendar, but I am having problems with some of the files.

This is an example of payload that keeps giving me errors:

{"summary":"Name","start":{"dateTime":"2023-02-16T14:30:00","timeZone":"Europe/Prague"},"end":{"dateTime":"2023-02-16T15:15:00","timeZone":"Europe/Prague"},"recurrence":["RRULE:FREQ=DAILY;UNTIL=20240131T235959;INTERVAL=28;WKST=SU"]}

Formatted for readability:

{
  "summary": "Name",
  "start": {
    "dateTime": "2023-02-16T14:30:00",
    "timeZone": "Europe/Prague"
  },
  "end": {
    "dateTime": "2023-02-16T15:15:00",
    "timeZone": "Europe/Prague"
  },
  "recurrence": [
    "RRULE:FREQ=DAILY;UNTIL=20240131T235959;INTERVAL=28;WKST=SU"
  ]
}

For this payload I get an "Invalid recurrence rule" error. I have checked the RFC and dont see any issue with this.

Solution

  • Answering my own question - the issue was with the "WKST=SU" parameter - apparently GCal API doesnt like it
