Rise v0.42.0 on JupyterLab v4.0.10 returns 404: Not Found

[posenato]

Hi to everyone!

Description

When I try to start a slideshow (clicking on the Rise icon present in an open notebook),
I obtain "404: Not Found".

Looking at the console, I noted that if the notebook file is /test.ipynb,
the server executes GET /rise/test.ipynb?activeCellIndex=0, but there is no /rise/ app working!

testCompressed.mp4

Reproduce

I installed:

• Python 3.11.7 using brew
• JupyterLab v4.0.10 using pip3
• Rise v0.42.0 using pip3 install jupyterlab_rise

Rise extension was not visible in the jupyter labextension list,
so I ran jupyter-labextension install jupyterlab-rise to see it.

Then,

1. I run the server by jupyter-lab in the directory containing the notebook.

[ServerApp] Jupyter Server 2.12.4 is running at:
[ServerApp] http://localhost:8888/

2. I open a notebook (test.ipynb) without any problem, and I can modify and save it.

3. I try to start a slideshow by clicking on the Rise icon present in an open notebook.

4. The browser shows a "404: Not Found" page.

5. In the log I see:

[ServerApp] 404 GET /rise/test.ipynb?activeCellIndex=0

I have just found a partial solution.
I think the problem was given by the fact I installed Python using brew and Jupyter lab using pip.
Since brew is fundamental to me, I decided to try to install all the stuff again, avoiding pip.

So, I removed all the installations of Python 3.11.7 and JupyterLab v4.0.10,
and I re-installed both using only brew.

brew installs JupyterLab v4.0.10 not as a cask but using a formula. Moreover,
it installs Python 3.12 for JupyterLab.

Then, I ran jupyter lab, and I installed jupyterlab-rise using the extension manager tab presented in the browser.
(If I use pip, jupyterlab-rise does not work as before, even if I install it using pip3.12).

I shut down the server (refresh is not sufficient) and started it again.

The rise extension works almost perfectly.
I have only the following missing files

I had the same issue - installing the jupyterlab extentions jupyterlab-rise via pip is not resulting in a working setup, installing via Jypuyter-Lab extension manager works.

[maltegrosse]

I had the same (404) issue running

• jupyterlab 4.0.2
• juperlab-rise 0.42.0

via jupyterhub on kubernetes.

Finally preinstalling the rise pluging via pip in the container solved the issue.

p.s. jupyterlab labextension install is deprecated and pip/conda should be used.
