Hi Everyone I am trying to intigrate docusign with salesforce. I am having one problem in my class when I am sending attachments of record. Code works fine when the record page is render as pdf.

I want to send attachments attached to  a record.

Apex class:
public with sharing class SendToDocuSignController {
    private final Opportunity opportunity;
   public String envelopeId {get;set;}
    private String accountId = '73ed93ba-5334-4983-9ba8-1515169d273a';

    public SendToDocuSignController(ApexPages.StandardController controller)
    {
        this.opportunity= [SELECT Id FROM Opportunity where id = :controller.getRecord().Id  ];
        envelopeId = 'Not sent yet';
        
        SendNow();
    }

   public void SendNow()
    {
        DocuSignAPI.APIServiceSoap dsApiSend 
            = new DocuSignAPI.APIServiceSoap();
        dsApiSend.endpoint_x = webServiceUrl;

        //Set Authentication
        String auth = '<DocuSignCredentials><Username>'+ userId 
            +'</Username><Password>' + password 
            + '</Password><IntegratorKey>' + integratorsKey
