ios - java.net.MalformedUrlException in itunes producer

Question

I am trying to publish an ePub on iTunes producer. The ePub file passes validation in epubcheck tool.

I am receiving the following error while submitting the epub:

Error: Internal error: java.net.MalformedURLException: unknown protocol: bundle schema/20/rng/container.rng" at Book/BookAssets

All my links have HTTP protocol specified without any typos.

I wish to publish on iTunes at the earliest. Not sure where this issue is coming from.

Answer 1

Go to Preferences - Advanced - uncheck Aspera and try again. It worked for me.

Answer 2

The solution for me was simply to remove underscores from filenames from xhtml files inside the ebook. Sounds strange but this solved the problem for me.
