Got the same error, any updates @jens-maus ?

Can you try to get a minimal ics File that can reproduce this error?

Tis error happensd when exDate is somehow strange becaue it contains something BUT mot a valid date object, so finding the reason would be ideal

@marsmaennchen @xRealNeon I had to put a fix in our application as the dates are returned from rrule.between() , not by ical.

                                        let dates=rrule.between(x,y) // get the list of rule matching dates
                    dates = dates.filter((d) => {    // filter out any garbage dates.. usually when TZ is trash
                        if (JSON.stringify(d) === "null") return false;
                        else return true;
                    });

this should be closed as a dup of

I am getting this error after updating to a new version of node-ical. I have isolated the version in which the behavior changed, it changed between 0.12.6 and 0.12.7. The attached code will recreate the error (works in versions earlier than 0.12.7)

const ical = require('node-ical');

const myevents = "BEGIN:VEVENT\r\nDTSTART:20230105T191500Z\r\nDTEND:20230105T193000Z\r\nRRULE:FREQ=WEEKLY;INTERVAL=1\r\nDTSTART:20230105T193000Z\r\nDTEND:20230105T194500Z\r\nRRULE:FREQ=WEEKLY;INTERVAL=1\r\nEND:VEVENT\r\n";

async function doit(){
    var events = await ical.async.parseICS(myevents);
}
console.log("Starting....");
doit()
  .then(() => {
    console.log("Finished....");
    process.exit(0);
  })
  .catch(err => {
    console.error(err);
    process.exit(1);
  });
