TypeError: Cannot read property 'redirect_uris' of undefined

问题

I want to write an app that can process some of my gmail emails that are labeled a certain way.

The example code here gave me a starting point for my code (which I've rewritten using promises instead of async await):

'use strict';

const path = require('path');
const { google } = require('googleapis');
const { authenticate } = require('@google-cloud/local-auth');

authenticate({
    keyfilePath: path.join(__dirname, 'key.json'),
    scopes: [
        'https://www.googleapis.com/auth/gmail.readonly',
    ],
}).then(auth => {
    google.options({ auth })

    gmail.users.messages.list({
        userId: "me",
    }).then((res) => {
        console.log(res.data)
    }).catch(err => {
        console.log(err)
    })
}).catch(err => {
    console.log(err);
})

Here are the steps I've taken so far:

• created a google cloud project
• created a service account with the owner role
• downloaded the key file from the service account and copied it to my code directory as key.json
• ran the code:

GOOGLE_APPLICATION_CREDENTIALS="$(pwd)/key.json" node index.js

Here's the error I am getting:

TypeError: Cannot read property 'redirect_uris' of undefined
    at authenticate (/home/user/dev/gmail-processor/node_modules/@google-cloud/local-auth/build/src/index.js:46:15)
    at Object.<anonymous> (/home/user/dev/gmail-processor/index.js:7:1)

    at startup (internal/bootstrap/node.js:283:19)
    at bootstrapNodeJSCore (internal/bootstrap/node.js:622:3)

It seems like it is expecting oauth credentials with a redirect url. Also, it seems redundant that I am exportingGOOGLE_APPLICATION_CREDENTIALS when I include keyfilePath when I call authenticate. What am I doing wrong, how can I get this code to execute successfully?
