Cloud function not getting triggered on database write

I'm writing cloud functions for the first time. I've setup the cli and everything, I want my function to trigger whenever there is an operation in my users collection. Here's what my code looks like: 

exports.testFn = functions.database.ref("/users/{userId}").onWrite(event => {
  console.log("testFn was Triggered!")
  console.log(`New write on user's collection: ${event.after.val()}.`)
})

I'm checking logs everytime I write/update something in my users collection there is no console statements or new logs in firebase dashboard. What's wrong? Also, How do i retrive userId value? Please help!

The code in your question is the onWrite trigger for realtime database. Since you are using cloud firestore then you can use the onCreate to read new data added :

exports.dbDelete = functions.firestore.document('/doc/path').onCreate((snap, context) => {
  const newData = snap.data(); // data that was created 
  const authInfo = context.auth;
});

authInfo will contain Authentication information for the user that triggered the function.
