Auth error [Cannot read property '0' of undefined]

[shrekmaster]

Trying to execute the code with client_secret json file. When I put the path in the code and try to execute after installing node module, get the following error

`/google-assistant/components/auth.js:26 const oauthClient = new OAuth2Client(key.client_id, key.client_secret, key.redirect_uris[0]); ^

TypeError: Cannot read property '0' of undefined at new Auth (/google-assistant/components/auth.js:26:91) at new GoogleAssistant (/google-assistant/index.js:33:18) at Object. (/google-assistant/examples/console-input.js:60:19) `

Any idea what I may be doin wrong here? client secret json file created and authenticated. It also works fine with another code that I have tried before
