Some books don’t load after update to 1.10.16

Hey @iberezansky,

I hope I find you well. I just updated to 1.10.16 and now I’m facing a number of issues. On Safari all controls of my books went missing – though that seems to be related to caching so I got them back.

However, some of my more recent books don’t load at all anymore with the console saying `”InvalidPDFException {message: “Invalid PDF structure.”, name: “InvalidPDFException”}
message: “Invalid PDF structure.”
name: “InvalidPDFException”
__proto__: Error`

You can check the issue yourself here: https://fslci.org/3d-flip-book/aslam-school-menu/

I tried to refresh the cache, resaved the book entry and tried multiple browsers but had no luck getting it back to work.

Would be great if you could look into why it’s not working anymore!

Kind regards, Philip
