I'm trying to set up an email provider with Next-Auth and Resend but i'm getting this error: Module not found: Can't resolve 'fs'.
Here's my Next-Auth setup for the provider:

EmailProvider({
      server: {
        host: process.env.EMAIL_SERVER_HOST,
        port: process.env.EMAIL_SERVER_PORT,
        auth: {
          user: process.env.EMAIL_SERVER_USER,
          pass: process.env.EMAIL_SERVER_PASSWORD,
        },
      },
      from: process.env.EMAIL_FROM,
    }),

And here's my server actions that should send the email:

'use server';

import { signIn } from 'next-auth/react';

import { successToast } from '@/components';
import 'server-only';

type EmailSignInData = {
  email: string;
};

export async function emailSignIn(formData: FormData) {
  const data = Object.fromEntries(formData) as EmailSignInData;
  await signIn('email', data);
  successToast(`Link sent to ${data.email}`);
}

I'm getting this error no matter if nodemailer is installed or not.
This error disappear when I comment the part in the Next-Auth setup.
I don't understand what is triggering this error as I'm following Next-Auth guide.
