My warm greetings, I'm trying to build an EPUB version of Active Prelude to Calculus however I'm encountering a lot of errors, after spending a whole day with it I got stuck at this part:
critical: [Errno 21] Is a directory: '/home/jj/prep/source/'
##################
Failed to build epub. Exiting...
----------------------------------------------------
While running pretext, the following errors occured:
critical: [Errno 21] Is a directory: '/home/jj/prep/source/'
----------------------------------------------------
Exception ignored in atexit callback: <function exit_command at 0x7faea901cee0>
Traceback (most recent call last):

SystemExit: 1
Things I tried: looking at the utils.py code but all I could find was that line 377 is a functin that prints sys.exit, I couldn't find any more useful information from the pretextcli output. I've also tried to generate the EPUB using windows, but I got an entirely different error which was:
critical: 'charmap' codec can't decode byte 0x9d in position 262: character maps to <undefined> but I was also not able to figure out where and how the error was taking place.
I'm not sure which debug logs to include, please let me know which I should include.
Thank you.

There are many errors about images in WeBWorK problems. Unclear if these might
be generated from TikZ or not.
But the failure may be due to trying to construct a cover image automatically,
those seem to be more serious errors and closer to when it all comes crashing down.
Can you provide a cover image? Any image? Should be documented. That might get
you past the error for now.
I don't know if the Active Prelude book has ever been built as an EPUB.

Okay thanks! I'll try it right now.
Yes, it does seem like they have never built an EPUB it seems but I really need wanted an EPUB version since I often don't have access to the internet.

Unfortunately, still the same error code :(. I'm not too sure if I did it correctly though.
I made a directory called cover and it has a file called cover.png
I then added an "<epub> <cover front=
cover/cover"/> </epub> on publication.

Late here, so just shooting in the dark.
Try putting ".png" onto the filename in the publication file.
And maybe the "cover" directory needs to be a subdirectory of "../assets" but less certain about this.

So I tried doing both of those and also I looked up the
"convert-im6.q16: attempt to perform an operation not allowed by the security policy `PDF' @ error/constitute.c/IsCoderAuthorized/421. convert-im6.q16: no images defined `/tmp/tmp64_fs0ll/cover.png' @ error/convert.c/ConvertImageCommand/3229" error and managed to solve it.

Please post the entire PreTeXt log each time you try a new approach, like you
did a while back.

Hello apologies for my late response I just had access to the internet. Thank you so much for your help unfortunately I have decided to give up in undertaking this task. I have just decided to settle for the local HTML builds.
Again, my great thanks to all of you!

Thanks, Bit, for all your work on this. I believe the presence of WeBWorK
problems producing images has not been considered in the EPUB conversion.
Leading to an unexpected failure.
I've put in a bit of (temporary) code to skip those images. I think there are
about 30 of these, judging from the number of validation errors.
I hope your internet is good enough to pick up:
https://pretextbook.org/beta/ac-prelude-epub-20230910/ac-prep.epub
If you can render it OK, it would be interesting to hear what reader you are
using. I can view it with Calibre on my desktop.
I'm going to start a thread about this on pretext-dev. You should be able to
read it publicly, and can request a membership if you want to contribute.
Sorry this was such trouble.
