Can not load extension's configuration list

[SDaoer]

Here is the problem I got:

However, the nbextension works well. So i guess it's caused by jupyter_nbextensions_configurator.
I think it is caused by duplicated item in its loading path, according to the only infomation displayed: [jupyter_nbextensions_configurator] error loading hinterland/hinterland.
The right path should be nbextensions/hinterland I guess.

Then I searched it:
grep -r "error loading"
./static/nbextensions_configurator/main.js: var msg = log_prefix + ' error loading ' + extension.require;

How could I fix this problem?

I have the same problem and cannot find a solution.

Windows 11, conda distribution, using conda environment.

Hi All,

struggeled with the same issue today. It was not a good idea to install nbextensions with conda
conda install -c conda-forge jupyter_nbextensions_configurator
because this conda-forge is using older version of jupyter-nbextensions-configurator (0.6.1), which is causing this issue.

The issue can be fixed, by using Anaconda Prompt and install newer version of jupyter-nbextensions-configurator:
pip install jupyter-nbextensions-configurator==0.6.3
