Аутентификация API пользователя приложения NextJS Dashboard

Я пытаюсь пройти этот учебник, но вместо получения данных через запрос PostgreSQL я хотел бы использовать API.

Я вызываю асинхронную функцию с помощью await, но она возвращает мне сначала неопределенное значение, а затем, когда API ответил, имя пользователя. Я хочу вернуть пользователя только один раз, чтобы аутентификация работала.

Вот мой код:

import Credentials from 'next-auth/providers/credentials';
import NextAuth from 'next-auth';
import type { User } from '@/app/lib/definitions';
import { authConfig } from './auth.config';
import { z } from 'zod';

async function getUser(email: string, password: string): Promise<User | undefined> {
  const axios = require('axios');
  axios
    .post(`http://localhost:4000/v1/auth/`, {email, password})
    .then((response: { data: any; }) => {
      console.info("response.data.user:", response.data.user);
      const userAuthenticated: User = {
        id: response.data.user.id,
        name: response.data.user.first_name + ' ' + response.data.user.last_name,
        email: response.data.user.email,
        password: ''
      };
      console.info("return userAuthenticated", userAuthenticated);
      return userAuthenticated;
    })
    .catch((error: { response: { data: { error: any; }; }; }) => {
      console.info("error:", error.response/*.data.error*/);
    })
    console.info("end of getUser");
}
 
export const { auth, signIn, signOut } = NextAuth({
  ...authConfig,
  providers: [
    Credentials({
      async authorize(credentials) {
        const parsedCredentials = z
          .object({ email: z.string().email(), password: z.string().min(6) })
          .safeParse(credentials);
 
        if (parsedCredentials.success) {
          const { email, password } = parsedCredentials.data;
          const user = await getUser(email, password);
          console.info('await getUser:', user);
          if (!user) {
            console.info('no user');
            return null;
          } else {
            console.info('user:', user);
            return user;
          }
        }
 
        return null;
      },
    }),
  ],
});

И что у меня в логах:

end of getUser
await getUser: undefined
no user
