Power Query SDK does not recognize OAuth authorization type

[collabsoft]

I am trying to build a custom connector for an OAuth2 API.  I have tried unsuccessfully for a day to get the SDK to allow me to set my credentials for OAuth.  The only thing that shows up in the list is Anonymous even after I have changed it and removed it from my pq file.

I get an error, "Invalid credentials: missing DataSourceKind, AuthenticationKind or the Query file."

Any help would be appreciated.

Thanks!
