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

amaaiia — Tue, 01 Oct 2024 11:07:26 GMT

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?

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

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.

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.

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.
