You'll need to decrypt your file using qpdf. An option to specify password was added to the underlying Python library after this https://github.com/socialcopsdev/camelot/issues/162#issuecomment-432040067. So I think it probably makes sense to the same option while uploading the PDF to Excalibur.

But, PDF i was trying to parse doesn't have any password protection.. Attached file for reference.. Unclaimed Unpaid Dividend-2013-2014-Interim.pdf
