Interval indexing on Distributed NDSparse doesn't work

[simonbyrne]

I can't get interval indexing to work on the TrueFX demo. I can't quite figure out the issue, but here's the stacktrace:

MethodError: no method matching isless(::IntervalSets.ClosedInterval{DateTime}, ::DateTime)
Closest candidates are:

When I ran into this, I was able to use a filter as a workaround..

(I know it is a bit late but maybe it is useful to somebody)
