Error parameter 'title' in book.json with iPad One

[Rexios]

I published a Newsstand App who work fine on iPad Three Retina (iOS 6) but on iPad One (iOS 5.1) I have this issue: [BakerBook] ERROR: param 'title' is missing. Add it to 'book.json'. When download magazine on iPad One I recive this message: There was an error opening this issue. Try downloading it again or contact the publisher.
Thanks

I've reverse-engineered your shelf.json URL from the url you posted above and downloaded the HPUB.

It looks to me like the book.json you have in the HPUB doesn't match the one you posted above: in the HPUB, your title is declared as an array, while it should be a string (it is correct in the version you posted above).

Btw, made the error message a bit more helpful in 21d5210.

That book.json is a test who I make after, thanks for your answer. I will exclude iPad One and iOS 5.1 from my app.

[Simbul]

Ok, I tested it on an actual iPad 1. The book.json you posted above works fine, but you have to remove the duplicated date parameter.

Thank you. It's work fine.
