Issue

Our app get many reports about this issue: Fatal: TypeError undefined is not an object (evaluating 'this._pending[n].meta')

This is our main code block doing with react-native-firebase:

export function saveUserInfo(data) {
  const ref = db.collection("users").doc(auth.currentUser.uid);
  return new Promise((resolve, reject) => {
    db.runTransaction(async transaction => {
      const doc = await transaction.get(ref);
      if (doc.exists) {
        transaction.update(ref, data);
      } else {
        transaction.set(ref, data);
      }
      return doc;
    })
      .then(doc => {
        db.collection("users")
          .doc(auth.currentUser.uid)
          .get()
          .then(
            userInfo => {
              resolve(userInfo.data());
            },
            error => {
              reject(error);
            }
          );
      })
      .catch(error => {
        console.log(error);
        reject(error);
      });
  });
}

Looks like some sort of error with regard to transaction handling. Not sure if it is a bug or not, but in this case, a get+update is equivalent to a set isn't it?

To create or overwrite a single document, use the set() method: https://firebase.google.com/docs/firestore/manage-data/add-data - seems inefficient and verbose to structure the code that way, and costs an extra read from firestore

The only time you should use transactions are: Transactions are useful when you want to update a field's value based on its current value, or the value of some other field https://firebase.google.com/docs/firestore/manage-data/transactions#transactions - but maybe I am missing something?

If you got right of the transaction there I bet the error would go away as well. Strangely that string did not appear in source at all, so I'm not sure where it is coming from. A full stack trace might help if restructuring code does not
