Web3 doesnt work with Cloud Functions

[Gabriel1590]

I´m trying to use a Cloud Function to send a transaction everytime that is new data in the datastore, first I try to obtain the GasPrice but everytime I connect to infura with web3 in the function gives me this error:

Error: Invalid JSON RPC response: ""

this is my code:

import * as functions from 'firebase-functions';
import admin = require('firebase-admin');
const Web3 = require('web3');

export const transaction = functions.database
.ref('/transacciones/{transaccionesId}')
.onCreate(async (snapshot) => {
    
    const url = 'https://mainnet.infura.io/v3/INFURAAPIKEY'
    const web3 = new Web3(url);

    console.log(web3)
