Cuando quiero usar el SDK de administración de firebase usando el siguiente código

 import * as admin from 'firebase-admin'; var serviceAccount = require("../services/serviceAccountKey.json"); admin.initializeApp({ credential: admin.credential.cert(serviceAccount), databaseURL: "https://voter-60a9f-default-rtdb.europe-west1.firebasedatabase.app" });

me sale este error

 BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default. This is no longer the case. Verify if you need this module and configure a polyfill for it. If you want to include a polyfill, you need to: - add a fallback 'resolve.fallback: { "util": require.resolve("util/") }' - install 'util' If you don't want to include a polyfill, you can use an empty module like this: resolve.fallback: { "util": false }

Este es solo uno de muchos. También tengo esto:

If you want to include a polyfill, you need to: - add a fallback 'resolve.fallback: { "path": require.resolve("path-browserify") }' - install 'path-browserify' If you don't want to include a polyfill, you can use an empty module like this: resolve.fallback: { "path": false }

y así....

Intenté reinstalar los módulos de Node pero no tuve suerte. Tampoco entiendo dónde debo agregar ese respaldo que sugieren. Y si lo encontrara, ¿necesito agregar esto para todos los módulos de nodo?

¡Gracias!
