in Nuxt I have the title error using auth v5. This is my current strategy:
The docs (https://dev.auth.nuxtjs.org/schemes/oauth2#codechallengemethod) says that you can use "plain" or "S256" as an option, I tried both but the error persists.
The only I cant manually get it work is by copy-pasting the oAuth in the url:
Compare that link to the following:
The only difference between the first and second link is that the first one actually works (I can login) and it doesn't have a challenge_method.
The second link doesn't work (it displays the google image above) but if you read the end of the link it has both the code_challenge_method & code_challenge
