ValueError after (rewrite) publication

[mmulich]

@edwoodward Reported not finding his content in legacy after publishing from authoring. He reported the following:

I published a derived copy of Concepts of Biology on beta. It was
successful.

http://beta.cnx.org/contents/[email protected]:1/Copy_of_Concepts_of_Biology

I searched for the content on legacybeta.cnx.org and it was not found.
I searched by title and by author.

I tried hitting the collection object in legacy and received a ValueError, the details are as follows:
