updateDoc: Uncaught FirebaseError: Invalid document reference-CodePudding

When updating a document in v9 of firebase/firestore I got an error and I've been following the official documentation and not sure what I'm doing wrong:

import { initializeApp } from "firebase/app";
import { getFirestore, updateDoc, doc} from 'firebase/firestore';
import firebaseConfig from '../utils/firestore';

const app = initializeApp(firebaseConfig);
const db = getFirestore(app);

function updateSeries(docID, name, desc) {

    const data = {
        name: name,
        desc: desc,
        lastUpdatedAt: Timestamp.now(),
    }

    const seriesDocRef = doc(db, "MY_COL", docID)


    return new Promise((resolve, reject) => {
        updateDoc(seriesDocRef, data).then(() => {
            resolve();
        }).catch((e) => {
            reject(e);
        })
    })
}

When I call this function I get this error:

errors.ts:94 Uncaught FirebaseError: Invalid document reference. Document references must have an even number of segments, but MY_COL has 1.

CodePudding user response：

If the values in passed into the doc function are undefined or falsy it can cause this error. Please check if the db and docID variables are defined in:

const seriesDocRef = doc(db, "MY_COL", docID)
