error.validation.sendPackage.noApprovals

Hi,

We are using this method to create an package

 DocumentBuilder documentBuilder = DocumentBuilder.NewDocumentNamed(doc.DocumentTitle)
                    .FromStream(new MemoryStream(doc.DocumentFile), DocumentType.PDF)
                    .WithId(doc.DocID)
                    .WithExtractionType(ExtractionType.TEXT_TAGS)
                    .EnableExtraction();

the problem is: some files don't contains the tag {{*esl:Signer1:Signature:size(200,20),offset(0,-11)}}

We are consuming one span esign api from pega. The package creation is failing with the below reason

Message: Cannot send package without approvals.

Message key: error.validation.sendPackage.noApprovals

Attaching the request data as a text file. Please help to resolve this.
