Reproduction URL

https://github.com/zluo01/next-auth-cognito

Describe the issue

Login with cognito will get following error error=redirect_mismatch from the cognito url. Cognito page shows An error was encountered with the requested page..

Only change I have made is create .env.local and clean up auth.js with one provider compare to the original next-auth-example.

Callback on cognito end is http://localhost:3000/api/auth/callback/cognito as suggested in https://authjs.dev/getting-started/authentication/oauth.

How to reproduce

Fill in the blank in .env.local then simply try to login with cognito.

Expected behavior

Successfully authenticate with cognito like V4.

See here, this can solve the error of authjs signin redirect failure in server form action.

export const signInWithGithubAction = validatedAction(
    signInWithGithubSchema,
        async (data, formData) => {
        const { redirect: redirectParma } = data
        const res = await signIn('github', {
            redirect: !!redirectParma,
            redirectTo: redirectParma ? redirectParma : undefined,
        })
    redirect(res)
  },
)

Key Points: redirect(res) at the fuction last.

fucking authjs , get up and work , I spent 3 hours on this,

Any update on this ? This is either a documentation error or actual bug that need to fix. As
shown above, this is not isolated to Cognito but other solutions as well.

@zluo01 have you figured this out?

Hi, this still doesn't work on the basic template using the nextauth cognito template getting "redirect_error"
It happens because a needed query params are missing such as redirect_url and grant_type

FYI, it was an issue before #12125 (comment).
