My guess is that it's this: multiValued="true"
Most sorting doesn't work on mutivalued fields as it's ambiguous what
sorting means; which value should be used? This isn't a very helpful
stack trace if that's the issue though I'll admit. There are some
JIRAs out there to allow sorting on, say, the min or max value here
but they're not in place yet..
May be totally wrong, but that's the first thing I'd look at. Come to
think I'm not entirely sure a dateRangeField is sortable for that
matter, haven't tried it personally.
BTW, I'd also define docValues for a field if I intended to sort on it.
Best,
Erick
