An error occurs when I set a redirect URL in the signIn callback

[kito-chall]

Your question
An error occurs when I set a redirect URL in the signIn callback
My [. .nextauth].js is as follows.
The problem is the return Promise.reject('/support') part.
Is there anything wrong with it?

I referred to this one.
https://next-auth.js.org/configuration/callbacks

What are you trying to do
I want to check the user account information when signing in and be redirected depending on the conditions.
true: go to the index("/") page.
false: go to support("/support") page.
