PowerBI Dataset Creation Error

Hello,

I'm running into a very odd error while creating Datasets for Power BI using Microsoft.AnalysisServices.  Basically I'm attempting to clone a dataset from an existing one by using Microsoft.AnalysisServices.Tabular's CopyTo() method to copy the Model from one dataset into another.  This has been working fine for us on our P2 instance that we setup but lately everything has stopped working and now throws the following exception:

Would anyone happen to know what limit I'm running into here?

Thanks,
