JavaScript errors in Custom connector

[ Edited ]

Hi everyone!

I developed a custom connector for Power BI and it works fine.

However I've got a little problem.

I'm connecting to a site through REST API. It uses OAuth2 authentification model. Unfortunately they have an error on their auth page.

So when I'm signing in I see the following window:




It does not matter my choice on this window. Anyway Auth process will finish successful. But the window irritates me. How can I disable this window?


Thanks in advance,

Re: JavaScript errors in Custom connector

Hi @rcyber

Which kind of your data source is?

See limitation here:

  • Implementing OAuth v2 authentication flow for a SaaS offering

Maybe your data source is not supported for OAuth v2 authentication, or you configure the wrong function for OAuth v2 authentication.

Check if you did it correctly?

Thank you for reply.

The datasource I'm connecting to supports OAuth2.
As I wrote above the connector works fine and authorization process completes successfull.
Just the auth page includes a javascript that contains an error and I see the message about that error.
I've made a little research and found out the Power BI desktop uses its own browser so I can't disable running javascript using standard setting of IE.
Any ideas?
