Dax query working in power bi desktop but generates error in power bi portal

[Donovin]

I am using the following DAX to calculate the month over month percentage differences for our costs. This DAX was working just fine until about last week. What I noticed is that in power bi desktop this works just fine but in Power bi portal it fails with the following error(see below)

What's even weirder is that this works for a smaller visual that only contains the difference in cost overall between this month and the previous month for all our azure subscriptions. But the second I change the matrix visual to include the azure subscription in the breakdown, it breaks the visualization with the following error.

Here showing the dax query working using a matrix visual(without adding the subscription name to the matrix). This works in both PBI desktop and portal

Here is what it looks like in power bi desktop(working)

Here is the error of the same visual in power bi portal

I am not sure if this is related to the DAX code. I tried removing the format command after reading some other posts but this resulted in more issues.

DAX below

=======================

MOM % Difference =

VAR CurrentPeriod =

    FORMAT ( MAX ( 'CalendarAuto'[Date] ), "yyyymm" )

VAR PreviousPeriod =

    CALCULATE (

        FORMAT ( MAX ( 'CalendarAuto'[Date] ), "yyyymm" ),

        FILTER (

            ALL ( 'CalendarAuto' ),

            FORMAT ( 'CalendarAuto'[Date], "yyyymm" ) < CurrentPeriod

        )

    )

VAR CurrentCost =

    SUM ( Azure_Data_All[cost] )

VAR PreviousCost =

    CALCULATE (

        SUM ( Azure_Data_All[cost] ),

        FILTER (

            ALL ( 'CalendarAuto' ),

            FORMAT ( 'CalendarAuto'[Date], "yyyymm" ) = PreviousPeriod

        )

    )

RETURN

    IF (

        AND ( CurrentCost <> 0, PreviousCost <> 0 ),

        DIVIDE ( CurrentCost, PreviousCost, 0 ) - 1,

        BLANK ()

    )
