Docusign API transformPdfFields & php - php

Question

I am having a problem getting the below code to work in my developer account. I keep getting the following error:
"ERROR calling webservice, status is:400 error text is --> { "errorCode": "ENVELOPE_IS_INCOMPLETE", "message": "The Envelope is not Complete. A Complete Envelope Requires Documents, Recipients, Tabs, and a Subject Line." }"
Anyone have an idea why this error is occuring? The "test.pdf" is located in the same directory as the docusign.php file that is the below code:

$integratorKey = " MY API KEY FOR DEMO ";
// construct the authentication header:
$header = "<DocuSignCredentials><Username>" . $email . "</Username><Password>" . $password . "</Password><IntegratorKey>" . $integratorKey . "</IntegratorKey></DocuSignCredentials>";

From what I can tell, the actual PDF Bytes of test.pdf are not being sent as part of this API request - therefore the error message is calling out the fact that you are referencing a document which is missing. Take a look at the PHP recipe examples for how you can read the PDF bytes in from a file and include it in your API request:
https://www.docusign.com/developer-center/recipes/request-a-signature-via-email
Specifically, this line and variable: $file_contents = file_get_contents($documentFileName);
