TypeError Cannot read properties of undefined (reading 'toString') in getOccurrenceDetails

[zomars]

Any pointers on why this might be happening?

 TypeError [22m Cannot read properties of undefined (reading 'toString')
error stack:[24m[22m
• ical.js:9004 getOccurrenceDetails
node_modules/ical.js/build/ical.js:9004:27
• 4270.js:244 <anonymous>

One of our users is using Zoho calendar and it seems like this error pops up when parsing a recurring event:
