Is this a problem with npm or JavaScript?

Hi everyone, I'm trying to figure out if this issue is related to JavaScript or npm. If there's a problem with my JS code, could someone please help me identify it?

PLEASE NOTE I used some code to get the current uid from Firebase. I'm not very experienced in JavaScript programming.

Here's the full code:

let functions = require('firebase-functions');

let admin = require('firebase-admin');

admin.initializeApp(functions.config().firebase);
var uid = event.params.uid;
exports.announceProduct = functions.database
 .ref('users/{uid}/notifications')
.onCreate(event => {
   let note = event.data.val();
  sendNotification(note);
  });

function sendNotification(note) {
 let title = note.title;
 let action = note.action;
 let user = note.user;

 let payload = {
notification: {
  title: 'user',
  body: 'action',
  sound: 'default'
}
 };
}

Error output in console:

Thank you so much!!

There seems to be a mismatch with opening and closing braces in this code snippet. Add three }'s at the end of the code block. Additionally, there are missing commas for the properties of the payload object. The arrow function syntax is incorrect for the event parameter in the onCreate method. While methods can accept functions as parameters, attempting to declare a function as a parameter is not allowed.

EDIT: Try implementing the following code:

let functions = require('firebase-functions');

let admin = require('firebase-admin');

admin.initializeApp(functions.config().firebase);
var uid = event.params.uid;
exports.announceProduct = functions.database
  .ref('users/{uid}/notifications')
  .onCreate(event => {
    let note = event.data.val();
    sendNotification(note);
  });

function sendNotification(note) {
  let title = note.title;
  let action = note.action;
  let user = note.user;

  let payload = {
    notification: {
      title: 'user',
      body: 'action',
      sound: 'default'
    }
  };
}

EDIT: To address your modified question, it appears that you are using the variable event in var uid = event.params.uid without defining it elsewhere.
