PdfFileEditor.Concatenate throws NullReferenceException

TaggedContentWithBrokenNumberTree.pdf (60.1 KB)

When I use the attached Pdf to be concatenated, I get a NullReferenceException.

sample code:

  var sourceDocument1 = new Document("TaggedContentWithBrokenNumberTree.pdf");
  var sourceDocument2 = new Document("TaggedContentWithBrokenNumberTree.pdf");
  var targetDoc = new Document();
  var pdfFileEditor = new PdfFileEditor
    AllowConcatenateExceptions = true,
    CopyLogicalStructure = true,
    CopyOutlines = true,
    KeepFieldsUnique = true,
    MergeDuplicateOutlines = true,
    OptimizeSize = false,
    IncrementalUpdates = true
  pdfFileEditor.Concatenate(new[] { sourceDocument1, sourceDocument2 }, targetDoc);
