Jupyter Lab server extension not found in binder #470

jld23 · 2021-04-08T18:49:45Z

Description

I have created a JupyterLab extension
that converts a SAS file (*.sas) to a Jupyter notebook (*.ipynb).

The extension works fine on my development systems (Ubuntu and OSX) but when I try and use it inside of binder I get 404 errors.

I had participated on an issue in January where @fcollonval referrenced issues but the links to that appear to have been merged. Which lead me to believe the issue was resolved.
I added the following line to my init.py but that didn't change the behavior
load_jupyter_server_extension = _load_jupyter_server_extension

Reproduce

Launch the binder instance -- https://mybinder.org/v2/gh/jld23/sas_kernel_ext/HEAD
In the root folder, right click on iris.sas
The first entry in the context menu should be 'Convert SAS to ipynb' select that menu entry.
Outside of binder, after a few seconds a pop-up appears saying the file was converted. Inside binder nothing happens.
If you look at the browser console you'll see something similar to this:

JupyterLab extension sas2nb is activated! index.js:15
XHRGEThttps://hub.gke2.mybinder.org/user/jld23-sas_kernel_ext-6frabum6/sas2nb/convert?1617907266164
[HTTP/2 404 Not Found 649ms]

Not a JSON response body. 
Response { type: "basic", url: "https://hub.gke2.mybinder.org/user/jld23-sas_kernel_ext-6frabum6/sas2nb/convert?1617907266164", redirected: false, status: 404, ok: false, statusText: "Not Found", headers: Headers, body: ReadableStream, bodyUsed: true }
handler.js:28
The sas2nb server extension appears to be missing.

The log states that the extension is missing but the following output doesn't support that:

Expected behavior

I expected the extension to work inside binder as it does outside of binder.

@jld23 you will find the information to make an extension compatible with the notebook server there:

Thank you @fcollonval!
For reference to any future users that incounter this problem.
The changes I needed to make from the cookiecutter setup are

Add the following code to `init.py in the root folder

# For backward compatibility
load_jupyter_server_extension = _load_jupyter_server_extension

take the extension json file (sas2nb.json in my case) and move if from jupyter-config to jupyter-config/jupyter_notebook_config.d and jupyter-config/jupyter_server_config.d. With minor changes needed in the notebook folder. Here are the respective files for my use case -- server and notebook.
Add these two lines to the data_files_spec in setup.py

("etc/jupyter/jupyter_notebook_config.d", "jupyter-config/jupyter_notebook_config.d", "sas2nb.json"),
("etc/jupyter/jupyter_server_config.d", "jupyter-config/jupyter_server_config.d", "sas2nb.json"),
