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,
