Value cannot be null. Parameter name: Data Source

Hi everyone,

 

I'm getting the following error, when I try to access a PowerBI-Dataset from a datahub:

 

The value cannot be NULL.
Parameter name: DataSource

 

I don't know why. PowerBI and the data gateway are up to date.

Is there a solution for this?

 

Thanks for your help.

I found the reason:

 

  • Using DirectQuery on datasets from “My workspace” isn't currently supported.
