this one mad me crazy!
I'm on PowerBI Desktop v.2.65.5313.841 (December 2018) connected live to SQL Server Analysis Services 2017 CU13 v.18.104.22.168.
If on a visual I try to filter using a basic filter or by a slicer, the visual being filtered shows an error "An unexpected exception occurred". The error doesn't occur if I use the Advanced Filter and set manually the condition (of course the same used on Basic filter or the slicer). The error doesn't happen if I point to an instance of Analysis Service 2017 RTM (22.214.171.1249), of course with same model and same data. If I try instead to import the model, then the version of Analysis Service used by PowerBI desktop is 126.96.36.199 and things works properly.
