Hi, I am also facing the same issue, Anonymous are there particular steps to resolve this?

Hi
Similar issue here.  It has arisen where I've published a PBIX file where the PBIX was built using SQL code.  Error message below

Hi,

we have the same issue here since today.

Error message is: "Login failed for user '<token-identified principal>'.. The exception was raised by the IDbConnection interface."

Connecting to Azure SQL Server (and ADX), both not working. Tried to set Basic Auth and AAD Auth, both with same result.

How was your issue above be resolved?

Thank you,

Christian

same issue and it occurs on one table in the data set and not the others. we have 3 tables in the data set, 2 work fine, only the 3rd table gives this error for any field/column we try to add to the power bi report. We checked, the same error happens when you try to use fields from the same table in Excel when retrieving data from this powerbi dataset.

If we open the dataset in PowerBI, we can use the fields from this table, it is only when trying to connect to this dataset from a power bi report or excel report that does not include the dataset in the same pbix file. 

Any anyone fixed this issue? I am facing the same issue 😞

This data source"{}" is missing credentials. Add the data source credentials by using the dataset settings page.This data source {0} is missing credentials. Add the data source credentials by using the {1}.

Trinity365 go to Settings-> Settings-> Datasets and then choose your dataset. After that add your sql server Username and password under datasource credentials (choose Basic as the authentication Method)

Goto the Settings -> Settings -> Datasource Credentials -> Edit Credentials and UNTICK the Report viewer can only access this data source with their own powerbi identities using DirectQuery.

Anonymous I have the same issue but your soluction works for me somehow. Thanks

Similar issue - there are multiple SQL data source connections in my report , how to identify which datasource caused this issue or is this error specific to direct connection data source ?
