get 404 with jupyterlab behind nginx

[cjbd]

Description

Hello, I follow this article to put my jupyterlab behind nginx, it's working fine

But when I install jupyterlab-git extension with pip, I always get this error message in the front end:

and from the console output, I can see error log like this:

[W 2023-03-20 03:38:17.634 ServerApp] 404 GET /git/settings?version=0.41.0&1679283497734 
(172.18.0.1) 0.81ms

Reproduce

1. pip install jupyterlab-git
2. reload jupyterlab
3. check error message in both front end and back end

Expected behavior

jupyterlab-git extension should work like without nginx

Hey @cjbd it is likely because the server extension part of this extension is not enable. Could you execute

jupyter server extension list

[cjbd]

@fcollonval thanks for the update, pls find command output, it's enabled

something that might not be relevant to this, i also had trouble with panel extension, it was giving simlar 404 error for /panel/...
just now i found that if i don't use nginx and launch jupyterlab from localhost, the panel extension is working fine, while git extension is still giving 404 error in the command console

[fcollonval]

Do you filter endpoints?

If yes you are likely filtering the endpoints of this extension?

[cjbd]

@fcollonval no, i don't know how to do that...

Has a similar issue here. My setup includes a jupyterhub as docker container that spawns jupyterlab containers. All reverse proxy-ed through a nginx server. Everything works fine until I wish to install a git extension. conda install works and after installation the output is:

$ jupyter server extension list
Config dir: /home/jovyan/.jupyter

Config dir: /opt/conda/etc/jupyter
--Other extensions omitted...
    jupyterlab_git enabled
    - Validating jupyterlab_git...
Package jupyterlab_git took 0.0258s to import
      jupyterlab_git 0.41.0 OK

Config dir: /usr/local/etc/jupyter

and

$ jupyter labextension list
JupyterLab v3.6.3
/opt/conda/share/jupyter/labextensions
        jupyterlab_pygments v0.2.2 enabled OK (python, jupyterlab_pygments)
        nbdime-jupyterlab v2.2.0 enabled OK
        @jupyterlab/git v0.41.0 enabled OK (python, jupyterlab-git)

Other labextensions (built into JupyterLab)
   app dir: /opt/conda/share/jupyter/lab

However when I reload the page this pops up and the logs from the lab container reads:

and the logs concerning the extension from the lab container reads:

[W 2023-07-17 07:15:31.012 ServerApp] 404 GET /user/alvinnnn/git/settings?version=0.41.0&1689578130935 (alvinnnn@my-IP-address) 23.85ms

and

Really not sure what was the issue but seemed very close to this

[fcollonval]

I would guess that your nginx is likely to filter out new API endpoints.

You should look at the proxy log.
