I found it on jgoguen github page.

Version 3.6.9 should be offered by calibre within the next hour or so to fix this ��

This plugin for me is broken. I accidentally installed the version 3.6.9 and all of my Kobo conversions are now broken. Here is the traceback- I am on 7.16.0 Calibre on Sonoma 14.5.

Since I updated the plugin the kepub conversion fails. The "normal" epub doesn't fail me, but it fails in the complicated ones with a lot of jpg and footnotes.
Thank God I found the old version (I don't know where you can see the version number) that appears in post #556 and now everything works again.
Here are the first few lines (out of more than 9000) of the Calibre error report log in case it helps:

I'm not able to reproduce this, but I also don't have a Mac to try it on. Please open a bug on GitHub and attach a full calibre debug log so I can try to dig in more. Based on what I can see, the error seems to be claiming that the string constant is actually a function... which makes no sense at all. When creating the debug log, do the minimum steps necessary to reproduce the bug.

There's nothing at all useful in these lines. Please open a bug on GitHub, providing as much information as possible, and include or attach a full calibre debug log. When creating the debug log, do only the minimum steps necessary to reproduce the bug. If it only happens with specific books, make sure to include a scrambled epub.

OK, I've found the problem.
The problem is with comments of the type:

<!-- COMMENT -->

in the html. If I remove them all, the conversion doesn't give any error.
I attach a minimal file so you can test it.

Fails happily here on my Windows 11 system with either the Kepub Output plugin or the KoboTouchExtended driver.

Does Kepubify work with the comment?

Yes but so do the 3.6.7 versions of Kepub Output and KoboTouchExtended.

Do you think we should go back to 3.6.7 as the official versions until whatever is wrong is fixed?

[jgoguen]

Version 3.6.10 should be offered by calibre within the next hour. This was caused by etree not following their own documentation, which was merry fun trying to chase down. But now there's also a test file including comments.

[jgoguen]

Version 3.6.11 should be offered by calibre in the next hour or so. This fixes an error converting some file types (like PDF).

[jgoguen]

Version 3.7.0 has been posted and should be offered by calibre within the next hour. This release brings an improvement to Kobo span generation and overall presentation by Shiandow.
