I've been working on a number of reflowable epubs created in InDesign. The others have opened and exported to .mobi using Kindle Previewer 3 just fine.
But this one gets the error message 'book conversion failed'.
The last line of the log says that the .mobi file built successfully, so check to make sure that the conversion really did fail.
However, using InDesign to create ePubs is asking for trouble. You'd be better off taking the ePub files and cleaning them up in Sigil, validating them, and then uploading them directly to KDP. I always upload ePubs; no need for .mobi conversion.
using InDesign to create ePubs is asking for trouble
Very true. A professional can do this, an amateur cannot.
I would export that ID file as an epub, then open the epub in Sigil and fix it there. A validated epub will always convert on the KDP. One that fails validation might work, or might not, and in any event will be refused by Apple and perhaps some other etailers.
(Don't trust KDP to publish a print edition. Don't trust CreateSpace to publish an ebook.)
*When you import a Word document using Place, you may find that all your
character styles have gone haywire if you have used any character styles
such as bold or italics in you doc. What happens is that all paragraphs
with bold or italics, for some reason, lose their end tags resulting in
great swathes of your paragraphs turned into bold or italics. To read more
about this see this link.
*ID will automatically(and without asking) encode and obfuscate any and
all embedded fonts in your epub.
That's just two well known quirks or problems in InDesign for ebooks. And
so if you choose to use InDesign for your ebooks then you will have to
take considerable time out to learn the app thoroughly(with all its
quirks!!). In the past, I have also used both InDesign and Jutoh for a
number of years but I now use Scrivener mainly because it gives the easiest
and cleanest conversion to epub that I've ever seen. And, for me at least,
Scrivener has the shortest learning curve of any word processor or ebook
converter out there. And no matter what ebook conversion app I use -- I
will always finish off my epub in Sigil before upload(I never directly
convert to Kindle mobi using ID's Kindle plugin or Scrivener). I always go
the epub route to Kindle.
Whenever you upload an epub to KDP you must always ensure that you upload the Product Image before you upload the epub. This is because the image in your epub is deliberately "suppressed" so that the Product Image can be used for you ebook image instead. It says as much in your kindlegen conversion report here:
Info(prcgen):I1052: Kindle support cover images but does not support cover HTML. Hence using the cover image specified and suppressing cover HTML in content . URL: /private/var/folders/sb/gt6dsdjs1v56v57ymhmj1ml00000gp/T/pYWst0/conv_tmp/KindleGen_temp_folder/mobi-8KX55L/OEBPS/cover.xhtml
So next time you upload your ebook in KDP, just make sure that you upload your Product Image as well and it should hopefully pass.
