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.
Solved! Go to Solution.
I found the reason:
Using DirectQuery on datasets from “My workspace” isn't currently supported.
Can Microsoft resolve this issue: Upgrade power bi desktop client to Version: 2.121.762.0 64-bit (September 2023).
