OAuth 2.0 and Power Query SDK

I am trying to create an OAauth 2.0 connector using Power Query SDK. A few issues I am facing.

AppTesting.PagedTable is not defined and when I run the project I get an error "The export AppTesting.Contents was exported multiple times."

It looks like there is a 'new' sdk for 'Visual Studio Code'  That is what I attempted to use after I failed to get the connector working with VS 2019 and the SKD.  Ill post that below (I just need one working)

https://learn.microsoft.com/en-us/power-query/samples/github/readme

https://learn.microsoft.com/en-us/power-query/handling-authentication

I have a few other projects, one I followed this tutorial and can post the code but I also receive other errors https://jussiroine.com/2019/02/building-a-custom-connector-for-power-bi-that-supports-oauth2-to-visualize-my-wellness-data/

Non of the tutorials I am able to get working
