In react native app (through Expo) using firestore permissions - request.auth is always null

Question

Here\'s my code:

firebase.auth().onAuthStateChanged((user) => {
    if (user) {
        console.log(\"We are authenticated now!\");
        firebase.fires         


        

Answer 1

Please log your UID and confirm it is not null. Then modify the permission rule as -

// Grants a user access to a document matching their Auth user Id
    service cloud.firestore {
       match /databases/{database}/documents {
         // Collection named "users", document named after the userId
       match /users/{userId} {
         allow read, write: if request.auth.uid == userId;
       }
     }
  }
