Hi everyone, 

I am trying to use data pipeline/ gen 2 to ingest data. However, When I use Service principle as Authentication kind it shows"Failed to login with OAuth token. Please try logging in again."

Dose any one know what is the issue?

Many thanks!

To what data source are you trying to connect? Does the service pincipal have enough permissions to get the data from the source?
