[Bug] Beta 19. Error generating the epub book

With Beta 19 I’ve tried to compile several projects to epub – all of which I had successfully compiled to epub with Beta 18. In every case after the popup that says Compiling, I get a popup that says “Error generating the epub book” and no epub file is created.

Windows 7 (64bit)

I’m having the same issue in Windows 10.

The same here…

Same here.
i choose 2 options, for compiling to epub:: default and e-book. Neither works. It starts the compiling process and then at some point it breaks and the error message comes up.

what did you do to the poor compiler?

windows 10, version 1903.

Sorry guys, we had to change the Zip library, which generates the ePub files, which have broken the ePub generation. We are fixing it and will release a new build within a week.

Guess we should just do it like Windows. Skip the odds and go for the evens. :stuck_out_tongue: :wink:

To be clear - both the .mobi and the .epub formats both fail to be compiled.

I use the mobi format for reading my work in progress on my Kindle, where it makes identifying errors and weaknesses much easier. So this is a critical feature. for me. Please update as soon as possible. Thanks.
