Github & Google Authentication in dev-mode Demo App

[Intevel]

This issue is a sub-thread of #1393

Github authentication does not work in dev-mode of the demo. Currently experimental, I could find that there is a problem in the callback, as soon as you click on Github login and are redirected back to the Nuxt App callback you get stuck in the login screen.

Currently I think the addAuthorize method is the problem,if I log the response and or error in the axios request it works. As soon as I take out the logging it doesn't work, I'm experimenting around and trying to solve the problem.

• Google auth (fix: Google authorization fix in dev-demo #1437)
• Github auth

In agreement with @bmulholland

This error is extremely confusing, I removed the logging again and rebuilt the module and there are no problems

Google Auth still not working:
400: invalid_request
Parameter not allowed for this message type: code_challenge_method
