First off: thanks for your work on this, I am messing around w/ Instagram for fun right now, but have a few ideas for an app I want to develop.

I was kind of confused by the documentation. So I have my script (using express) logging in and getting a valid access_token. In my Instagram.oauth.ask_for_access_token callback I am setting the access_token as:

Instagram.set("access_token", params["access_token"]);

Then when I try to call Instagram.users.self() without any parameters, I get an error. I looked through the code and it looks like it should be defaulting to Instagram_config["access_token"] but it doesn't get that far - it gets to:

  if ((require != null) && (params[require] != null) || (params['access_token'] != null) || (params['client_id'] != null)) {
        return params;

(sorry, compiled - I'm not so much into CS yet)

And it dies on that line - here's the trace:

TypeError: Cannot read property 'access_token' of undefined

I am not sure if this is by design, but later you're checking for this._config['access_token'] so maybe a check if params === undefined is needed?

Anyhow, thanks again for your work.


I’m thinking you’re right about the params check @chiefy. I'll get that added — thanks for the heads up.



did this get added? I'm getting the same issue now...


I believe I did @joemccann, but this might be related to #6, which is in the works. I’ll check while there.


I fixed it...i'll submit a pull request
