error with tabular measures in powerbi.com

I have a SQL Server 2014 Tabular model connected to PBI through an enterprise gateway.

I have created a simple SUMX measure in my tabular model

SUMX(FILTER(FactVehicleCounts,RELATED(DimSalesChannel[SalesChannelDesc])="CertifiedPreOwned"),[Vehicle Counts])

I can see the measure and use the measure in Power BI Desktop. I can also publish the report succesfully.

When I go to the PBI service and I click on the report, I get an error for the visual

For the life of me I cannot figure out what the PBI service has an issue with. Anyone else running into this? It also happened on a calcualted column I added to my DimDate table (simple concatenation of values)
