Hiya,
I get this message when searching across indexes where the item type
does not exist at all. If I run my query below just on the index where
this object does for sure exist then I do not get this error.
The issue might be also that I would like elasticsearch to silently
fail when the facet cannot be cast on an object.
I notice that even if data exists on one of the three indexes, the
search still fails.
I am open to further discussion.
Thanks and have a warm winter,
Bryan Green
Specifically, it is the long UPCID field that is causing this issue.

When you facet on a field across index types, they need to be of the same
field type (string, long). You can name the field differently.
