I am trying to create a lookerbot. I want my node app to reach looker but I keep getting this error:

node:internal/process/promises:279
            triggerUncaughtException(err, true /* fromPromise */);
            ^

[UnhandledPromiseRejection: This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). The promise rejected with the reason "AxiosError: Request failed with status code 401".] {
  code: 'ERR_UNHANDLED_REJECTION'
}

Node.js v17.9.0
error Command failed with exit code 1.

This is my code:

const axios = require('axios');
const qs = require('qs');
const SLACK_KEY = 'xoxb-1234';
const LOOKER_URL = 'https://xyz.abc.looker.com:19999/api/3.0/';
const LOOKER_CLIENT_ID = 'mnbv';
const LOOKER_CLIENT_SECRET = 'lkjh'

axios.get(LOOKER_URL, {
    params: {
      'clientId': LOOKER_CLIENT_ID,
      'clientSecret': LOOKER_CLIENT_SECRET
    }
  })
  .then(function (res) {
    console.log(res);
  })

I am not sure what my error is and how to make my node app reach my looker instance.
