Thanks to all of you related,
I have uploaded the page.
https://www.fablab-shinagawa.org/archive/index.html
when you click "パラメトリック" - which means "parametric"- tab,
you would see the list of our parametric designs, and again when you click a design,
you would link to the page includes openjscad model.

What webserver are you using?

Did you make any special changes to the configuration of the webserver?

Did you have any issues installing the web site? Make any changes?

Thank you for your support.

you have given an url that is not a script, it fails on syntax parsing.

and if you take a look into network tab you will see why

you need to fix your proxy script and web server config so it returns js file that you expect instead of perl source of your proxy script.

The console says that :
DevTools failed to load source map: Could not parse content for https://www.fablab-shinagawa.org/jscad/packages/web/drawer.css.map: Unexpected token < in JSON at position 0

also in network tab you can see the url that is called and if you open it in a diffferent tab:
https://www.fablab-shinagawa.org/jscad/packages/web/remote.pl?url=https://fablab-shinagawa.org/jscad/designs/canHolder.js

it looks like your perl script is not executed. You need to cofigure web server to run it instead treating as static asset

ERROR:
Unexpected token # in JSON at position 0
Stack: SyntaxError: Unexpected token # in JSON at position 0

The URL you showed as not accessible, has to be :
https://www.fablab-shinagawa.org/jscad/designs/petbottleOpener.js
Modeling scripts has no problem.
Please check this link :
https://openjscad.xyz/#https://www.fablab-shinagawa.org/jscad/designs/petbottleOpener.js

And I always have following error, when I put the link like :
https://www.fablab-shinagawa.org/jscad/packages/web/index.html#https://www.fablab-shinagawa.org/jscad/designs/petbottleOpener.js

ERROR:
Unexpected token # in JSON at position 0
Stack: SyntaxError: Unexpected token # in JSON at position 0

https://www.fablab-shinagawa.org/designs/petbottleOpener.js

That URL needs to work, i.e. the file should download and show in the browser.

So, the webserver configuration is incorrect.

Here's an example...

https://openjscad.xyz/examples/core/colors/colorCube.js

The webserver must support PERL, as there's a PERL script that runs on the webserver. (I can assist if you are using Apache)

After configuring and testing the webserver, copy 'remote.pl' to the webserver, and move into the base directory of the jscad website.

We use...

/var/www/openjscad.xyz/public_html/remote.pl

In addition, a new directory needs to be created called 'cache'. The PERL script downloads files and puts the file into this directory.

this url would work then for my proto that has no proxy
https://3d.hrg.hr/jscad/three/threejscad2.html?uri=https://fablab-shinagawa.org/jscad/designs/fruitsHolder.js

for exampe if I put your script to gihtub as a gist it works
https://3d.hrg.hr/jscad/three/threejscad2.html?uri=https://gist.githubusercontent.com/hrgdavor/08e61d2014ed7b62078fa9106380f634/raw/815d639e16bfa4e88e65e2e50b6772bc17cab35a/fruit.js

In this page, I edited the script temporary so that we are able to manipulate our modeling sources via help menu.

Anyway, I would like to know the process to activate using those URLs such as :
https://fablab-shinagawa.org/jscad/index.html#https://fablab-shinagawa.org/jscad/designs/fruitsHolder.js
without errors.

Thank you.

FYI, you are the first person trying this, i.e. installing the full website.

This is going to take some extra steps because there's some setup for the website, as well as special files for making the website function properly.

Are you sure that a 100% copy of the JSCAD website is necessary?
