I recently upgraded Firebase to 10.12.4 and now have this error which isn’t allowing me to compile.

import firebase from 'firebase/compat/app';
import "firebase/compat/auth";
import "firebase/compat/database";
import "firebase/compat/firestore";
import "firebase/compat/storage";


const firebaseConfig = {
  apiKey: "xxx",
  authDomain: "xxx",
  databaseURL: "xxx",
  projectId: "xxx",
  storageBucket: "xxx",
  messagingSenderId: "xxx",
  appId: "xxx",
  measurementId: "xxx",
};

firebase.initializeApp(firebaseConfig);

firebase.firestore().settings({ experimentalForceLongPolling: false, cacheSizeBytes: firebase.firestore.CACHE_SIZE_UNLIMITED, merge: true });

export const storage = firebase.storage(); 
export default firebase;

This has worked with no problems in the past – but am wondering why it now throwing this error, and how to fix it?
