Hi,

I am getting this error  (OAuthException - We couldn't parse your query string because it was improperly formatted) . 

This error only occurs in Power BI Service throug on premises gateway.



But in Power BI desktop it's worked fine.

Error from OP Gateway:

GatewayPipelineErrorCode=DM_GWPipeline_UnknownError

Hi @Anonymous ，
Which authentication mode do you use?OAuth2.0 or service principle?

If you are using a B2B user for authentication, do other users get the same error when connecting to the same data source?

Best regards,
