Hi,

Thank you for reaching out to the DocuSign Community.

A blank signature can be caused by the signer choosing to draw their signature. When drawing their signature, they click on the draw box and only choose one pixel. This can happen on a computer or a mobile device. 

If the signer indeed adopted a correct and legible signature and the envelope got completed but the signature is still missing from the final copy you might want to test downloading the envelope within the Manage tab of your account and selecting the Combine all PDFs and verify the downloaded document, you can also do another test by logging into the DocuSign UI and sending a test envelope to yourself and verify the outcome. 

If the issue persists and you indeed were using the correct code and the test envelope had the same results, you might want to create a case with our Support Team to verify the information for you. To ensure that the DocuSign Support team handles your request in the most efficient manner, please include all relevant information in your support case (the complete PDF, the affected Envelope ID, and details of the affected recipient).
