Elasticube has no data. Please rebuild the Elasticube

I've seen this happen, mostly when I've been throwing giant pivots with lots and lots of data and/or complicated filters at an Elasticube. If I see the error in the (Windows) Server Console, detaching and re-attaching the cube folder will tend to fix it at least temporarily but (following advice I've heard myself often enough from Sisense Support) I would review my Pivots and Elasticube Schema so they are not presenting or having to query too much data
