Salesforce-Docusign在分配后不附加文档

Question

我正在尝试进行DocuSign和SF集成。目前，我有一个自定义按钮，用于创建文档并将其发送给收件人。效果很好，但现在我要附加分配的文档。因此，我尝试正确配置DocuSign连接到SalesForce的连接，并创建一个对象并设置要附加文档的对象。但是，即使分配了文档，我的SF对象也没有任何附件。

这是我的课程，负责将我的文档发送给我的收件人：

public with sharing class SendToDocuSignController {
private final Contract contract;
public String envelopeId {get;set;}
private String accountId = 'MYACCOUNTID';
private String userId = 'MYUSERID';
private String password = 'MYPASS';
private String integratorsKey = 'MYKEY';
private String webServiceUrl 
    = 'https://demo.docusign.net/api/3.0/dsapi.asmx';

public SendToDocuSignController(ApexPages.StandardController controller)
{
    this.contract = [select Id, CustomerSignedId, AccountId, ContractNumber 
    from Contract where id = :ApexPages.currentPage().getParameters().get('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 
        + '</IntegratorKey></DocuSignCredentials>';
    System.debug('Setting authentication to: ' + auth);

    dsApiSend.inputHttpHeaders_x = new Map<String, String>();
    dsApiSend.inputHttpHeaders_x.put('X-DocuSign-Authentication', 
        auth);

    DocuSignAPI.Envelope envelope = new DocuSignAPI.Envelope();
    envelope.Subject = 'Please Sign this Contract: ' 
        + contract.ContractNumber;
    envelope.EmailBlurb = 'This is my new eSignature service,'+ 
        ' it allows me to get your signoff without having to fax, ' +
        'scan, retype, refile and wait forever';
    envelope.AccountId  = accountId; 


    // Render the contract
    System.debug('Rendering the contract');
    PageReference pageRef = new PageReference('/apex/RenderContract');
    pageRef.getParameters().put('id',contract.Id);
    Blob pdfBlob = pageRef.getContent();     

    // Document
    DocuSignAPI.Document document = new DocuSignAPI.Document();
    document.ID = 1;
    document.pdfBytes = EncodingUtil.base64Encode(pdfBlob);
    document.Name = 'Contract';
    document.FileExtension = 'pdf';
    envelope.Documents = new DocuSignAPI.ArrayOfDocument();
    envelope.Documents.Document = new DocuSignAPI.Document[1];
    envelope.Documents.Document[0] = document;

    // Recipient
    System.debug('getting the contact');
    /*Contact contact = [SELECT email, FirstName, LastName 
        from Contact where id = :contract.CustomerSignedId];*/

    DocuSignAPI.Recipient recipient = new DocuSignAPI.Recipient();
    recipient.ID = 1;
    recipient.Type_x = 'Signer';
    recipient.RoutingOrder = 1;
    recipient.Email = 'email';
    recipient.UserName = 'Teste';

    // This setting seems required or you see the error:
    // "The string '' is not a valid Boolean value. 
    // at System.Xml.XmlConvert.ToBoolean(String s)" 
    recipient.RequireIDLookup = false;      

    envelope.Recipients = new DocuSignAPI.ArrayOfRecipient();
    envelope.Recipients.Recipient = new DocuSignAPI.Recipient[1];
    envelope.Recipients.Recipient[0] = recipient;

    // Tab
    DocuSignAPI.Tab tab1 = new DocuSignAPI.Tab();
    tab1.Type_x = 'SignHere';
    tab1.RecipientID = 1;
    tab1.DocumentID = 1;
    tab1.AnchorTabItem = new DocuSignAPI.AnchorTab();
    tab1.AnchorTabItem.AnchorTabString = 'By:';


    DocuSignAPI.Tab tab2 = new DocuSignAPI.Tab();
    tab2.Type_x = 'DateSigned';
    tab2.RecipientID = 1;
    tab2.DocumentID = 1;
    tab2.AnchorTabItem = new DocuSignAPI.AnchorTab();
    tab2.AnchorTabItem.AnchorTabString = 'Date Signed:';

    envelope.Tabs = new DocuSignAPI.ArrayOfTab();
    envelope.Tabs.Tab = new DocuSignAPI.Tab[2];
    envelope.Tabs.Tab[0] = tab1;        
    envelope.Tabs.Tab[1] = tab2;        

    System.debug('Calling the API');
    try {
        DocuSignAPI.EnvelopeStatus es 
        = dsApiSend.CreateAndSendEnvelope(envelope);
        envelopeId = es.EnvelopeID;
    } catch ( CalloutException e) {
        System.debug('Exception - ' + e );
        envelopeId = 'Exception - ' + e;
    }

基本上，通过此控制器，我渲染对象数据pdf并将其附加到新的DocuSign文档，然后通过API将其发送到DocuSign。之后，当收件人分配我的文档时，会在我的DocuSign连接日志中触发一个事件，但是我的对象没有关联的附件。

我遵循了this文档来配置我的Connect对象

我的DocuSign配置：

This is my Connect object configuration

This is my Connect SF configuration

This is my Connect log

如果需要其他信息，请告诉我。

谢谢。
