Can't export to HTML using VSCode Jupyter Extension

[m1guelperez]

uHey,

I can not export my jupyter notebook when using the VScode extension. However, using the following command in the terminal it works:
jupyter nbconvert --to html notebook.ipynb

OS: Arch-Linux 5.19.12-arch1-1
VSCode: 1.71.2
Python: 3.10.4

@m1guelperez One thing to try here. For import export we don't necessarily use the environment associated with the current notebook. Instead we might be using a global environment. Could you check by running the Jupyter: Select Interpreter to start Jupyter Server command and then setting it to the same environment that you are using to run nbconvert from the terminal? If that is already the correct env (or if the export fails in the same way) I can dig into the logs to look.

[m1guelperez]

Hey!

I checked it and it was set to the correct env. Also in the stack trace seems to be the correct one: [NbConvertApp] Looking for jupyter_nbconvert_config in /home/miguel/miniconda3/envs/ml-classification/etc/jupyter.

This env is on: /home/miguel/miniconda3/envs/ml-classification/bin/python

Therefore, the issue remains.

EDIT:
The problem was that I did not specify the file ending. If I add .html. Then it works. But maybe it is possible to make this automatic?
