http 400 file: expecting a file upload

[applemate]

I have a problem trying to add a file to dropbox. The db log says 400 error code. What am I missing here?

This is my code:

    function save_to_dropbox() {

        // http://localhost:8888/mamaohla/test/save_to_dropbox/11109644961428152252_thumb.png
        // adding 11109644961428152252_thumb.png from root/photo/post folder
        // to dropbox root folder

        $thumb = $this->uri->segment(3);
        $path= FCPATH.'photo/post/';
        $filename = $path.$thumb;

        $dbpath = '';

        $params['key'] = $this->config->item('db_app_key');
        $params['secret'] = $this->config->item('db_app_secret');
        $params['access'] = array('oauth_token'=>urlencode($this->session->userdata('oauth_token')),
                                  'oauth_token_secret'=>urlencode($this->session->userdata('oauth_token_secret')));

        $this->load->library('dropbox', $params);

        $obj =$this->dropbox->account();

        // print_r($obj);

        // add thumb to dropbox
        $this->dropbox->add($dbpath, $filename);

    }

And this is dropbox error log

This is similar to another issue someone just posted. I can't replicate it. I saw a thread on another github library where they said updating the PHP version solved it. BenExile/Dropbox#67
