planview connection error

Was this issue ever resolved? I see that this question was posted two years ago, but I'm getting the same error whenever I try to connect to Planview using the "Enterprise One - PRM" data source in Power BI. I can connect via the "Planview Enterprise One - CTM" connection (although I then get a different error trying to preview the data tables) using my credentials, but I cannot connect to PRM using the same credentials. (My Planview admin assured me that I have authorization within Planview to allow the data connections though, and I can clearly see that I'm authorized to the Portfolio and Resource Management functionality within Planview given that I manage projects and resources within the app.)

I really need to be able to connect PBI to Planview and create reports as the "out of the box" reports in Planview are not providing management with the level of resource capacity planning details they're looking for. How do I get past this error?
