I include PDF's in the epub as follows:
<object data="Authorship.pdf#view=FitV" type="application/pdf" style="width:100%; height:100vh"></object>

"#view=FitV" is necessary for the pdf to automatically fit on the display/monitor without being cut off.
However, this leads to the above error message.

Looks like a bug, I'll have a look for the next maintenance release. Thanks for the report!

Presumably, the error occurs everywhere where a URL is given but there is no link:

<embed src="bla#xyz" pluginspage="bla#xyz"
<link href="bla#xyz"
<iframe src="bla#xyz"
<script src="bla#xyz"
<img src="bla#xyz"
<form action="bla#xyz"
<object data="bla#xyz"
<picture src="bla#xyz" srcset="bla#xyz"
<source src="bla#xyz" srcset="bla#xyz"
<video src="bla#xyz" poster="bla#xyz"
<audio src="bla#xyz">
