Power Query SDK is crashing after try to login again for OAuth v2 in Unit testing

Hello, I'm trying to run the unit tests, a have a couple of functions are calling to an API that require authentication.

The first time is OK, I authenticate (MyConnector.Contents() ). but then the Error message tab comes up again to request the authentication for another endpoint (MyConnector.AnotherFunction()).

 When I try to login again, Visual Studio crash.

Hi @f1729 

From the screenshot, it seems your custom connector doesn't define the proper authentication type, please follow a clear guide how to implement Oauth2 authentication type for custom connector:


Best Regards



Thank you @v-juanli-msft 


I already have my connector working with oauth authentication, but the problem is when I'm running the unit testing in the *.query.pq file. 


From the screenshot it appears your data source kind is showing up as "Web", rather than your custom connector. This likely means that you're trying to call Web.Contents outside of your custom data source function. 


I'm trying to consume an OAuth2 API, however, at a certain stage a Pop-Up opens asking for Login and Password on the page. Is it possible to login with Power Query?
