I have 15 dataflows (on the Power Bi Premium Servcie) that I use to get large amounts of data through an API. 13 of them work fine. They are all exactly written the same, except of course the "source". So all the steps in them are just copies.
The two that do not work, I get this error when I refresh:
"Expression.Error: We cannot convert the value null to type Record."
When I look in the preview, there seem to be no error.
I have copied the queries to Power Bi desktop, and they run perfectly.
What am I missing?
Solved! Go to Solution.
