Hi, when loading a DOCX with certain content, this exception is thrown during the load:

System.ArgumentNullException: 'Value cannot be null.

Parameter name: owner'


The load command used is:

 syndoc.WordDocument workingDoc = new syndoc.WordDocument(infilename, FormatType.Docx);



The document must have a content control that includes a hyperlink.


Example document attached to reproduce the issue.

I have found a workaround by adding a single space after the last text in the control, and before the closing tag for the control, the error can be avoided.
