I am just started learning node js. I am trying to host a firebase function. But when I query database (PGSQL using node pg) I am getting forever loading. Please see my code..

exports.myfunction = async(req, res) => {
  const {Client} = require('pg');
  const client = new Client({
    user: "dfgdfgdfg",
    host: "IP Address given",
    database: "sdfdsfsd",
    password: "fsdfdsf",
    port: "54321",
  });

 

// res.send('hi'); works fine here

    const rest = await client.query("SELECT id,unique_withdraw_id,asset_id,amount,address FROM withdrawals WHERE transfer_network = $1 AND status=$2 LIMIT $3",
    ['ETH', 'Accepted', 20]);


// res.send('hi'); does not work here, the browser keeps loading...

}
