Error: 14 UNAVAILABLE: Getting metadata from plugin failed with error: invalid_client

[itachiRedhair]

In the project credentials are retrieved from home directory as follows:

const homedir = require('homedir');
const deviceCredentials = require(`${homedir()}/.config/google-oauthlib-tool/credentials.json`);

What I am trying to do is populating deviceCredentials Directory in the code itself:

const deviceCredentials = {
  client_secret: 'xxxxxxxxxxx',
  refresh_token: 'xxxxxxxxxxx',
  scopes: ['https://www.googleapis.com/auth/assistant-sdk-prototype'],
  client_id: 'xxxxxxxxxxxxxxx',
  token_uri: 'https://accounts.google.com/o/oauth2/token',
};

I am getting following error:

How are you obtaining the deviceCredentials values? There may be an issue with how you obtained the client_id.
