Sessions not saving inside function call

Inside my AuthController, I am doing the following:

request.post({url: 'https://graph.api.smartthings.com/oauth/token', form: authData} , function(err, resp, body){
    info = JSON.parse(body);
    req.session.accessToken = info.access_token;

    getEndpoint(req.session.accessToken, function(err, resp) {
        if(err) {
            //TODO: Handle error
            console.log(err);
        } else {
            req.session.endpointUri = resp;
        }
    });

    console.log("endpoint " + req.session.endpointUri);

    res.view('test', {
        accessToken: req.session.accessToken,
    });
});

As you can see, I am trying to set 2 sessions, accessToken and endpointUri.

The accessToken session saves just fine, and I can access it from other controllers, however my endpointUri does not save.
I've tested the function and resp is being returned, and if I log out the session straight after setting it within the else statement it works.

If I try and log out the session outside of the else statement, it is undefined.

What is happening here?

You want access the session value on an Async operation which is not completed when you return your view. Try:

request.post({url: 'https://graph.api.smartthings.com/oauth/token', form: authData} , function(err, resp, body){
    info = JSON.parse(body);
    req.session.accessToken = info.access_token;

    getEndpoint(req.session.accessToken, function(err, resp) {
    if(err) {
        //TODO: Handle error
        console.log(err);
    } else {
        req.session.endpointUri = resp;

        console.log("endpoint " + req.session.endpointUri);

        res.view('test', {
        accessToken: req.session.accessToken,
        });
    }
    });


});

By the way, this using nested callback is not the good pattern, try using bluebird library or asyncawait.
