GetToken: Failed to get token authenticator for auth type: ServicePrincipal

[amaaiia]

Hi.

I have some Data Pipelines with a Semantic Model refresh activity, authenticating with Service Principal. One day, it stopped working, and it shows the following error since then:

I've created a new Data Pipeline with just Semantic Model refresh activity, I've configured it and still the same error. If I authenticate with my organizational account, it works, but I need to authenticate by Service Principal.

The PowerBIDatatsets connection that I'm using is correct, I've checked it in connections list. What does this error mean?

Where can I get more logs? The pipeline is as simple as this: 

The activity is configured as follows:

And the connection: 

Notice the connection is ok, because if I manually change the key to a no valid key (just to test), I get this error:

So yes, the client id and key are VALID.

can you confirm whether the client secret is still valid for the client ID? Meaning it has not expired

I have the exact same problem with a Service Principal that has been created just now:

Service Principal has been granted Contributor access in the Azure Data Factory I am trying to connect to.

Hi,

I know is valid because of two reasons:

1. When I create a new connection using these keys I don't have any errors. For example, If I change a character in the secret, it returns an error message that is not valid.

2. I have another SQL Server connection created to access data in a Lakehouse as data connection for semantic model, using service principal authentication, and it works.
