An M partition uses a data function which results in access to a data source different from those defined in the model

问题

I have about 5 Web Service (API) calls I am using, and none of them are working for me...

4 of them are returning this error:

An M partition uses a data function which results in access to a data source different from those defined in the model.

But guess what, these very same Web Services work in Power BI desktop.

I am in VS working on an AAS Tabular model.

Please help - I think this is just a VS bug...

We had a similar problem but with getting data from an SQL Server in an on-premise SSAS. We used Sql.Database function in M (PowerQuery) code. We managed to solve this problem by declaring this SQL Database as a Data Source and then referencing this Data Source in the M code.
