Is anyone here?
If this is not an issue, please close this.
Thanks.

I tried to reproduce the problem, but found it strange.

The order of my execution commands is as follows:

$ npm -v
6.13.4
$ node -v
v12.9.1
$  uname -a
Linux t480 5.14.5-gentoo-x86_64 #1 SMP Fri Sep 17 22:51:55 CST 2021 x86_64 Intel(R) Core(TM) i7-8550U CPU @ 1.80GHz GenuineIntel GNU/Linux

And I build up a test environment:

I've run both npx honkit build and npx honkit serve 3 times in the above order respectively, but can't reproduce this issue.

So I can only make a speculative bug fix update.

The file I've test:
cjk_nested_test.zip

Could you provide more detailed demo files or try the latest version?

[vowstar]

Please try https://github.com/vowstar/gitbook-plugin-uml/releases/tag/1.2.12

[yumeto-yamagishi]

Thanks for your checks.
I found the very strange phenomena. I can't explain reproduce procedure.

The first time, unzip the file you provided and try to build, then the issue did NOT happen.
In the same testing folder I replaced all files with mine, then the issue DID happen. (This is the expected result.)
Again in the same folder I replaced all files with unzipped ones you provided, then the issue STILL DID happen!!

This means, my source, config or environment is a trigger of causing issue, but another factor (something like cache?) exists.

My MacOS env (where the issue happens):

$ npm -v
6.14.14
$ node -v
v14.17.4
$ uname -a
Darwin yumeto 19.6.0 Darwin Kernel Version 19.6.0: Tue Aug 24 20:28:00 PDT 2021; root:xnu-6153.141.40~1/RELEASE_X86_64 x86_64

Note:

• The issue still happens after updating to [email protected] with my source.

[yumeto-yamagishi]

I can't provide the source causing the issue because it's owned by my customer.

I'll try to create a sample that always cause the issue.
But it may take a time.

According to my verification, this happens if book.js is configured with root and is not in the same directory as docs.
