Internal error: looking up invalid data on a dense spool.

Does anyone have a clue what this error message relates to? Only seems to appear on the service, not in desktop.   Internal error: looking up invalid data on a dense spool.

    Hi JR19 

    This error shows up only in the Power BI Service when certain measures (like SUMX with CALCULATE) run, even though they work fine in Desktop, I think the fix is to simplify or rebuild the measure, republish the dataset, or try a new workspace and if it still fails, it’s a backend issue.

     

    Did it work? 👍 A kudos would be appreciated
