TypeError: Cannot read property 'passwordCredentials' of undefined

[clsahongraph]

I have configure all credential for upload file and save in Bluemix Object Storage with the help this solution, code here

...
...
 var pkgcloud = require('pkgcloud-bluemix-objectstorage');
 var fs = require('fs');

app.post('/upload', function(req, res) {
    // Create a config object
    var config = {};
    // Specify Openstack as the provider
    config.provider = "openstack";
    // Authentication url
    config.authUrl = 'https://identity.open.softlayer.com/';
    config.region= 'dallas';
    // Use the service catalog
    config.useServiceCatalog = true;
    // true for applications running inside Bluemix, otherwise false
    config.useInternal = false;
    // projectId as provided in your Service Credentials
    config.tenantId = '234567890-0987654';
    // userId as provided in your Service Credentials
    config.userId = '098765434567890';
    // username as provided in your Service Credentials
    config.username = 'admin_34567890-09876543';
    // password as provided in your Service Credentials
    config.password = 'sdfghjklkjhgfds';

  //This is part which is NOT in original pkgcloud. This is how it works with newest version of bluemix and pkgcloud at 22.12.2015. 
    //In reality, anything you put in this config.auth will be send in body to server, so if you need change anything to make it work, you can. PS : Yes, these are the same credentials as you put to config before. 
    //I do not fill this automatically to make it transparent.
    config.auth = {
        forceUri  : "https://identity.open.softlayer.com/v3/auth/tokens", //force uri to v3, usually you take the baseurl for authentication and add this to it /v3/auth/tokens (at least in bluemix)    
        interfaceName : "public", //use public for apps outside bluemix and internal for apps inside bluemix. There is also admin interface, I personally do not know, what it is for.
        "identity": {
            "methods": [
                "password"
            ],
            "password": {
                "user": {
                    "id": "098765434567890", //userId
                    "password": "sdfghjklkjhgfds" //userPassword
                }
            }
        },
        "scope": {
            "project": {
                "id": "234567890-0987654" //projectId
            }
        }
    };

    //console.log("config: " + JSON.stringify(config));

    // Create a pkgcloud storage client
    var storageClient = pkgcloud.storage.createClient(config);


    // Authenticate to OpenStack
    storageClient.auth(function (error) {
        if (error) {
            console.error("storageClient.auth() : error creating storage client: ", error);
        } else {

            //OK
            var new_fname = dir + "__" + file.originalname;
            var readStream = fs.createReadStream('uploads/' + file.filename);
            var writeStream = storageClient.upload({
                container: 'chat-files',
                remote: new_fname
            });

            writeStream.on('error', function(err) {
                // handle your error case
                console.log("concluido o upload com erro!");
                console.log(err);
            });

            writeStream.on('success', function(file) {
                // success, file will be a File model
                console.log("concluido o upload com sucesso!");
            });

            readStream.pipe(writeStream);                
        }
    });

}
...

I corrected the issue with this package :

It works as per documentation after I used this package.

pkgcloud-bluemix-objectstorage

It fixes the AUTH issue.
