Error help: "Invalid input object: NoneType"

MichaelGray · 02-02-2010, 09:56 AM

Hello,

I'm trying to create my first manual ePub, in a bid to understand it all a bit better and hopefully end up with a cleaner, leaner ePub file.

So far I've successfully tagged my source InDesign file with XML and converted that to a valid XHTML document, and generated all the other bits of the folder to be zipped into epub (following the useful tutorial at http://www.jedisaber.com/eBooks/tutorial.asp)

But something is not right - Digital Editions complains of "minor errors" and then doesn't even show it, while Calibre adds it to the library but says "Invalid input object: NoneType" when I try to view the file.

Can anyone point me in the right direction?

Thanks
Michael

Try using Calibre to convert this ePub to ePub and see if that might fix whatever is wrong.
