ConnectFirestoreEmulator() throwing Connection WebChannel transport errored

Question

I have a react native app, which i am developing using Expo. In my project, i run firebase firestore emulator and I want to connect my application to the emulator. I use the expo GO app on my phone and call the following function (after initialising the app):

connectFirestoreEmulator(db, "127.0.0.1", 8080);

When i try to add data to the firestore using:

const joinDesqr = await addDoc(colRef, {
        userID: userID,
        level: level,
        timeslots: timeslots,
        days: days,
      })

i get a warning like this, and the data is not inserted to the firestore emulator database:

If i don't run the ConnectFirebaseEmulator() function, the application perfectly adds data to my real firestore database. My reasoning is that i should put the IP of my actual computer where the local emulator is running. The default value is "localhost" instead, which is not working either.

I have tried experimentalForceLongPolling as some threads suggest, but without success:

const db = initializeFirestore(firebaseConfig, {
  experimentalForceLongPolling: true,
});
