Power BI Service Refresh Failure: OAuth authentication method isn't supported for this data source

hvnter 

I got same error this afternoon!! Dataset refresh okay. Have raised a ticket to IT Admin and Microsoft support team. 

Hey, we are seeing the same issue on our end trying to connect to dataflows/semantic models.

I'm not getting OAuth issues, but I and several others on Reddit are reporting issues with semantic model refreshes such as the following:

Data source error: Object reference not set to an instance of an object.. The exception was raised by the IDbCommand interface. Table: <Random table name from my data set>.

My gut says this is something on the MS side

Same issue with OAuth error. Happening with imported model from SSAS

Direct Query on SSAS seems fine

we are facing same issue, getting this on our Fabric Capcity Metrics:

and similar errors mentioned earlier:
Data source error: Object reference not set to an instance of an object.. The exception was raised by the IDbCommand interface. Table: <Random table name from my data set>.

We are also getting the same issue that started just today. IT is happening with some reports and can' t pinpoint the source causing it.

Same issue here: "ServerError_DMTS_OAuthFailedToGetResourceIdError" in PowerBi web interface for reports, PowerBi Desktop Client Loads reports ok. 

Hi hvnter 

 It looks like the credentials you're using have expired, but we will need more detail to help.

What's the data source type, what account type are you using to authenticate etc

Yeah, exact same issue here... the report refreshed fine this morning, but now I'm getting this same error message when trying to open it

Same issue here
