Getting Internal oAuth error. Immediate help is appreciated

[bkarthik3525]

Hi,
I have a web application which already working with google strategy, Now I am in need of integrating Azure AD login to my application.
I followed the strategy configuration as stated in http://www.passportjs.org/packages/passport-azure-ad-oauth2/ , while running the app I can able to see the AD login and after login I am getting Internal oAuth Error

here is the code snippets

I couldn't get the exact error when using the passport.authenticate in middleware approach, So I used as inside my request handler.

here is my config parameters

The important thing is when I use MSAL library, everything going smooth, which means the after login the access toke and user details can be retrieved from the response.
here is the response when using MSAL.

NOTE: My network is behind proxy and I whitelisted .microsoftonline.com
