Cannot export to PDF

[juanjosegarciaripoll]

Environment data

• VS Code version: 1.73.0
• Jupyter Extension version (available under the Extensions sidebar): 2022.9.1303220346
• Python Extension version (available under the Extensions sidebar): 2022.18.2
• OS (Windows | Mac | Linux distro) and version: Windows
• Python and/or Anaconda version: Miniconda
• Type of virtual environment used (N/A | venv | virtualenv | conda | ...): conda
• Jupyter server running: Local

Expected behaviour

I execute the command to export a notebook to PDF, it should run without problems, but apparently an extension that is not automatically installed is required.

Actual behaviour

The extension aborts with a message captured below

Steps to reproduce:

[NOTE: Self-contained, minimal reproducing code samples are extremely helpful and will expedite addressing your issue]

1. Create a minimal conda environment
2. Create a notebook in Visual Studio
3. Let the extension install Jupyter's requirement
4. Execute the command to export to PDF

Logs

Output for Jupyter in the Output panel (View→Output, change the drop-down the upper-right of the Output panel to Jupyter)

I have the same issue with VS Code V1.75.0 and Jupyther Extension Version V2023.1.2000312134.

Export is aborted withe the message for further information see output. But there is no information posted.

from searching around, it looks like this may be a problem in a specific nbconvert library from this comment.

You might be able to resolve this with an uninstall/reinstall of that package as is what helped here: #4347 (comment).

Let us know if you're still having trouble with this.
