I've tried many methods such as
const admin = require("firebase-admin");
admin.initializeApp();
const db = admin.firestore();
const docRef = db.collection("users").doc(dynamicDocID).get()
const docRef = db.collection("users").doc(dynamicDocID)
as well as many other and keep getting undefined or a promise that never seems to be resolved
Cant seem to find proper docs on this if anything
Since Cloud Functions for Firebase are written in Node.js, have a look at the Node.js examples in the Firestore documentation.
Based on that:
const docRef = db.collection("users").doc(dynamicDocID)
const document = await docRef.get()
console.log(document.id, document.data())
Or if you can't use await:
const docRef = db.collection("users").doc(dynamicDocID)
return docRef.get().then((document) => {
console.log(document.id, document.data())
})
