PBI RS:kpi not supported format

[KiwiGonzales]

Hi!

we have some KPI's which worked with reportingservices 2016. after updating to PowerBi Report-Server I got an error of "unsupported format". the error occurs in the "values" field (value from dataset). the value is just simple text an I can choose it:

But after click this message is showing:

("an error occurs", "unvalid or not supported format")

Has anyone any idea?

thanks,

Peter
