DirectQuery for PowerBI datasets - Preview feature: Error on testing

Hi,

 

I have just upgraded to the December 2020 release to test out the 'DirectQuery for Power BI datasets and Analysis Services' preview feature.

 

After connecting to my Dataset and then attempting to connect to a new data source I receive the following error message when adding the dataset as a local model:

 

"DirectQuery to AS - DW Common BI Model
The given key was not present in the dictionary."
 
Does anyone have any pointers?
 
Regards

    "I also had this problem.
    It happens when you have in the dataset tables without columns, only measures.

    To workaround it I added a dummy column to those tables."
