NEST-Desktop behind a proxy

[kreuzert]

Hi everyone,

I would like to use NEST-Desktop behind a proxy, but the javascript functions are looking for the assets on the wrong path. Is there a way to tell NEST-Desktop where to look for the assets?

Context:
I created a Docker image based on jupyter/datascience. I added a server proxy extension for JupyterLab and installed nest-desktop in a conda environment. (Dockerfile is here)

However, I'm able to run nest-desktop start in my JupyterLab Terminal. But if I want to open it at the path https://<my_jupyterhub_server>/user/user_name/server_name/proxy/8000/ it is looking for the assets at https://<my_jupyterhub_server>/hub/assets/... , while instead it has to use the path above.

Is there any way to configure nest-desktop in that way? I assume that there are more usecases for this, for example running NEST-Desktop behind a nginx proxy at a specific path.

Thanks,
Tim

Sorry for late response. Your issue is a special one.
I only started NEST Desktop from bash but I assume
that it would be possible to start it from the Python interface.

I notice two things in your screenshots:

1. You have to start NEST Server before starting NEST Desktop. Starting NEST Server from Python will cause some unidentified error that crash the flask server instance. I fixed this problem, when I use older Flask ( < v1.0).
2. I registered that NEST Desktop is not able to load json from assets folder.
   Is it a kind of permission issue of Jupyter notebook?

I am forward hearing from you whether jupyter notebook is able to work with NEST Desktop and NEST Server.

I will continue my tests with the nest server in the next days. But I remember to started it, maybe not in the runs with the screenshots.

The second point is exactly the reason, why I opened this issue. NEST Desktop is looking at the wrong place for the assets folder. I want NEST Desktop to look here: "https://jupyter-jsc.fz-juelich.de/user/[email protected]/my_jupyterlab_name/proxy/8050/assets" instead of "https://jupyter-jsc.fz-juelich.de/hub/assets". Is there a way to change the prefix path for the assets folder?
