Unable to send attachment - Salesforce Docusign API - salesforce

Question

I am trying to send attachment (record has one attachment) in opportunity record via Apex and Docusign "CreateAndSendEnvelope" API.
But I am getting this error "The DocuSign EnvelopeId:Exception - System.CalloutException: Web service callout failed: WebService returned a SOAP Fault: An Error Occurred during anchor tag processing. Invalid document faultcode=soap:Client faultactor=https://demo.docusign.net/api/3.0/dsapi.asmx"
Below is the piece of code used.
// Render the contract
System.debug('Rendering the contract');
PageReference pageRef = new PageReference('/apex/RenderContract');
pageRef.getParameters().put('id',contract.Id);
//Blob pdfBlob = pageRef.getContent();
Attachment att = [SELECT Id, Name, Body, ContentType FROM Attachment WHERE Parentid = :contract.Id LIMIT 1];
Blob pdfBlob = att.Body;
// 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 = contact.Email;
recipient.UserName = contact.FirstName + ' ' + contact.LastName;
// 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;
}
Any ideas how to overcome this error?
Thanks.

Answer 1

The Original Poster's (OP's) comment is
it worked fine on rendering the whole record to pdf...but now i tried sending attachments only instead of whole record.. i started to get this error.
So my guess is that the envelope request has a document problem.
Best way to debug: see what is being sent to the DocuSign platform.
Try the beta API logger or the regular logger. Then add the log to your question by editing your question.

This problem came across me with same error .
" An Error Occurred during anchor tag processing. Invalid document faultcode=soap:Client faultactor=https://demo.docusign.net/api/3.0/dsapi.asmx "
you need to replace anchor tab string with desired string given in your attached document where signature is required.
Replace :
tab1.AnchorTabItem.AnchorTabString = 'By:';
tab2.AnchorTabItem.AnchorTabString = 'Date Signed:';
To :
tab1.AnchorTabItem.AnchorTabString = 'Signature label in your document';
tab2.AnchorTabItem.AnchorTabString = 'Signature label in your document';
