await is only valid in async functions and the top level bodies of modules

December 21, 2022

I’m trying to connect to the google client API, but it’s saying await is only valid in async functions regarding the const client. But there is an await and async?

const express = require("express");
const { google } = require("googleapis");
require("dotenv").config();

let testENV = JSON.parse(process.env.GOOGLE_ENV);

const app = express();

app.get("/", async (req, res) => {
  const auth = new google.auth.GoogleAuth({
    keyFile: "testENV",
    scopes: "https://www.googleapis.com/auth/spreadsheets",
  });
});

const client = await auth.getClient();

app.listen(3000, (req, res) => {
  console.log("Running on 3000");
});

>Solution :

We can only use await, inside the async function. Here you have used the await but that is not inside the async function.

Here you can use then-catch, instead of the await

const express = require("express");
const { google } = require("googleapis");
require("dotenv").config();

let testENV = JSON.parse(process.env.GOOGLE_ENV);

const app = express();

app.get("/", async (req, res) => {
  const auth = new google.auth.GoogleAuth({
    keyFile: "testENV",
    scopes: "https://www.googleapis.com/auth/spreadsheets",
  });
});

const client = auth.getClient()
.then((client) => {
  console.log(client)
  app.listen(3000, (req, res) => {
  console.log("Running on 3000");
});
})
.catch((error) => {console.log(error)})

const express = require("express");
const { google } = require("googleapis");
require("dotenv").config();

let testENV = JSON.parse(process.env.GOOGLE_ENV);

const app = express();

async function start() {
  app.get("/", async (req, res) => {
  const auth = new google.auth.GoogleAuth({
    keyFile: "testENV",
    scopes: "https://www.googleapis.com/auth/spreadsheets",
  });
});

const client = await auth.getClient();

app.listen(3000, (req, res) => {
  console.log("Running on 3000");
});
}

start()
