I think this might be because you have a typo in your input EPUB. If you check your OPS/fb.opf file in your input EPUB you will notice it has this:

<package version="2.0" unique-identifier="PrimaryID" mlns="http://www.idpf.org/2007/opf">

and I would say instead of "mlns" it should have "xmlns" (did not test it to be honest):

<package version="2.0" unique-identifier="PrimaryID" xmlns="http://www.idpf.org/2007/opf">
