DocuSign "unable able to convert document" when i create create envelope with word file

Question

I am creating a DocuSign envelope and I pass docx file for signing process. But I get the error code "UNABLE_TO_CONVERT_DOCUMENT". I am passing extension docx in document object. This is my code

Dim doc1 As Document = New Document()
Dim doc1b64 As String = Convert.ToBase64String(buffer)
doc1.DocumentBase64 = doc1b64
doc1.Name = "Sample"
doc1.FileExtension = "docx"
doc1.DocumentId = "1"
envelopeDefinition.Documents = New List(Of Document) From {
doc1
}

For Pdf i passed like this

Dim doc1 As Document = New Document()
Dim doc1b64 As String = Convert.ToBase64String(buffer)
doc1.DocumentBase64 = doc1b64
doc1.Name = "Samplepdf"
doc1.FileExtension = "pdf"
doc1.DocumentId = "1"
envelopeDefinition.Documents = New List(Of Document) From {
doc1
}

Is any other place need to specify document extension? I am using sdk ver 5.9.0 for your reference. When using pdf file no problem. But same word file pass through DocuSign UI (website) no problem.

Answer 1

You need to include .docx as a part of the document's name:

doc1.Name = "Sample.docx"

Unfortunately, including just the FileExtension attribute is not enough.
