Javascript – Reference Error: Property firebase doesn't exist

LOG [ReferenceError: Property ‘firebase’ doesn’t exist]

I didn’t change anything in my code but all of a sudden, when I try to create a user, using firebase’s authentication, it says property ‘firebase’ doesn’t exist. The promise doesn’t kick in after creating the user. What can I do?

const signUp = async () => {
    await getDocs(createdUserDoc)
    .then((user) => {
        if(user.convoCode === convoCode){
            setConvoCode(Math.random().toString(36).slice(6))
        }
    })
    await auth.createUserWithEmailAndPassword(email, password)
    .then(createdUser => {
        setDoc(doc(db, `users`, auth.currentUser.uid), {
            email,
            convoCode,
            id: createdUser.user.uid,
            timestamp: firebase.firestore.FieldValue.serverTimestamp(),
            bio: "I don't got a bio🥱",
            image: 'https://firebasestorage.googleapis.com/v0/b/convoapp-91392.appspot.com/o/4112f225-1b3f-47a3-b2eb-d2b99dfd3996.jpg?alt=media&token=5c8177f3-51f7-4d77-a761-ef6b5c6ce1a0',  
        })
        router.push('/authentication/AddUsernameScreen')
        setPassword('')
        setEmail('')
    })
    .catch((err) => {
        toastRef.current.show({
            type: 'error',
            text: `${err.message}`,
            duration: 5000
          })
        console.log(err)
        return;
    })
}

I’ve tried rolling back my code to days before today, but it still gives the same thing. I don’t know what to do because I didn’t change anything in my code. And I’m under pressure to push the update over the weekend

    You’re mixing the newer modular API and the classic namespaced API in your access to Firestore.

    Based on that, the error likely comes from this line:

    timestamp: firebase.firestore.FieldValue.serverTimestamp(),

    In the modular API, you need to import the top-level serverTimestamp function from the Firestore SDK and then use it as:

    timestamp: serverTimestamp(),

    To close out this topic, there were a couple of issues with the initial post. We moved to this discussion.

    Summary:

    • remove combined use of async/await and .then()/.catch() ; recommended to just use async/await
    • was using both react-native-firebase and firebase in the same Expo/RN app ; recommended just using react-native-firebase ; detailed explanation of the options is here.
    • code calling getDocs() was not using return value correctly

    @mac concluded that he will refactor the code taking into account all of the above.
