version, all

when rrule (provided by node-ical, now called ical) gets confused, it returns an array of invalid date objects from the between function.

 dates: [ null,null,null,null....]

the code checking them then crashes because of the invalid date object.

there are an unknown number of causes

like this event from in the past

Fixes: #3256 

BUT.. the testcase is inconclusive.. as the code FAILS without the fix,
BUT somehow RETURNS 0 entries..
in real life run the node helper fails, and all calendar processing
stops.
