title: Docusign API, document content not showing
body: <p>I am trying to use a <strong>sandbox demo Docusign api v2.1</strong> to create an envelope, everything works great except the actual content in the document does not show in the signing view. </p>
  
  <p>I've tried various PDF files as well as Word files. Also verified that my base64 encoding of the binary file is valid.</p>
  
  <p>Here is my code for the document section of the envelope definition:</p>
  
  <pre><code>"documents": [
      {
        "documentId": "1",
        "name": "docusign test document",
        "fileExtension": "pdf",
        "documentBase64": "#base64FileContent#"
      }
    ],
  </code></pre>
  
  <p>Appreciate if anyone experienced this before could give me some pointer.</p>
