Issue to access sender fields from the docusign api

Here are the steps that i followed:

First, I have created brand new docx file and added the {{placeholder}} which is sender fields per the article here manually.I folllowed below article how to create sender fields

Sample sequence with manually created sender field syntax. reference: https://developers.docusign.com/docs/esign-rest-api/esign101/concepts/documents/document-generation/

• I did step 1 to 4 manually (steps from above link)

• creating document with the sender fields,

• added document to the template in the docusing portal.

• I have created the envelop in the status created.

• **Issue is **: when i call the getEnvelopeDocGenFormFields API with the correct template id and document id (1), i get no form fields.I did verify for sure i am calling the correct template and document id. you can verify in the attachment with the placeholders.

Yes I created document in the .docx format added place holders/sender fields in the format {{XXXX}} and uploaded to the portal (my account is personal developer account)

Can you please let me know where am i missing?
