Can't get codebird to upload

I am usign recommended code structure to upload a video for a tweet. I get the following error:

Can't find HTTP method to use for "upload".
in /home/oldtuber1/myoldtv.com/cmsCSoft/codebird-php-develop/src/codebird.php on line 1752.

This happenes whether a reference a relative or absolute path to the video, or use physical path
Can you tell me what I am missing?
