Firestore adapter with NextJS middleware

[MartinPit]

I'm using a Firebase adapter in my NextAuth config as described in the docs:

import NextAuth from "next-auth"
import Google from "next-auth/providers/google"
import Credentials from "next-auth/providers/credentials"
import { FirestoreAdapter } from "@auth/firebase-adapter"
import { signInWithEmailAndPassword } from "firebase/auth";
import { auth as appAuth } from "@/lib/firebase/config";
import { firebaseAdminConfig } from "./lib/firebase/admin-config";

export const { handlers, signIn, signOut, auth } = NextAuth({
  providers: [
    Google,
    Credentials({
      name: "firebase",
      credentials: {
        email: { label: "e-mail", type: "email", required: true },
        password: { label: "password", type: "password", required: true }
      },
      async authorize(credentials) {
        if (!credentials?.email || !credentials.password) return null;
        try {
          const user = await signInWithEmailAndPassword(
            appAuth,
            credentials.email as string,
            credentials.password as string
          );

          if (user) {
            return {
              id: user.user.uid,
              email: user.user.email,
              name: user.user.displayName
            };
          }

          return null;
        } catch {
          return null;
        };
      },
    })
  ],
  adapter: FirestoreAdapter(firebaseAdminConfig),
});

I also want to protect some pages when users are not signed in. I'm using the middleware approach as described in the Protecting Resources section of the docs.

My middleware.ts:

export { auth as middleware } from "@/auth"

When I try to run the app, I get the following error:

Module build failed: UnhandledSchemeError: Reading from "node:process" is not handled by plugins (Unhandled scheme).
Webpack supports "data:" and "file:" URIs by default.
You may need an additional plugin to handle "node:" URIs.
Import trace for requested module:
node:process
./node_modules/google-logging-utils/build/src/logging-utils.js
./node_modules/google-logging-utils/build/src/index.js
./node_modules/gcp-metadata/build/src/index.js
./node_modules/google-auth-library/build/src/index.js
./node_modules/google-gax/build/src/fallback.js
./node_modules/@google-cloud/firestore/build/src/index.js
./node_modules/firebase-admin/lib/firestore/index.js
./node_modules/firebase-admin/lib/esm/firestore/index.js
./node_modules/@auth/firebase-adapter/index.js
./src/auth.ts

I figured out that it's because firebase-admin is being imported in the auth.ts (for the config to the adapter) so if I don't use the adapter or don't import it in middleware.ts the app works.

How can I make both the middleware an FirestoreAdapter work at the same time?
