using twitter api with firebase cloud functions [duplicate]

Question

I have been assigned on a task to fetch all tweets from a certain hashtag and send that data to my application. So I decided to use firebase cloud functions, I generated the key needed for the twitter api. I also tested get my homepage using postman status and worked, however my issue now when I test my code on good cloud functions I cant get it to work and the error message when I try this end point:

Error: could not handle the request

https://us-central1-don.cloudfunctions.net/api/

or

https://us-central1-don.cloudfunctions.net/api/statuses/user_timeline

and this is my code on firebase cloud functions

const functions = require('firebase-functions');
const admin = require('firebase-admin');
const express = require('express');
const Twitter = require('twitter');
admin.initializeApp(functions.config().firebase);



const client = new Twitter({
    consumer_key: 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx',
    consumer_secret: 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx',
    access_token_key: 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx',
    access_token_secret: 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
});

const app = express();

/* Express */

app.get('/', function(req,res){
    client.get('statuses/user_timeline', {screen_name: 'nodejs', count: 5}, function (error, tweets, response) {

        if (!error) {
            response.send({ title: 'Express', tweets: tweets })
        }
        else {
            response.send({ error: "this is error: " + error })
        }
    });
});
// Cloud Function
exports.api = functions.https.onRequest(app)

Hope anyone can suggest any solutions, thanks.

Update: here is my function console where it also throws an error:

api Function execution took 8 ms, finished with status code: 404
