Can't use my own client_id and client_secret

[billyhalim]

I am walking through this tutorial. In the following code,

ig.use({
    client_id: 'e0e51c60672c4f09abe28c46c71a3a7a',
    client_secret: 'db11c575a8ae4f1aa90a03ba1d1345d8'
});

When I use my own client_id and client_secret, it appears an error when I accessed the site. The error is forEach is undefined. However, when I use the client_id and client_secret from the tutorial, it works well (like the code above). So, why can't I use my own client_id and client_secret ?

Thanks,
Billy

I have found out the solution. We must use the access token if we want to use our own client_id and client_secret
