vscode: "Failed to save 'x' file name is not supported by Jupyter.."

Environment data

  • VS Code version: 1.59
  • Jupyter Extension version (available under the Extensions sidebar): v2021.8.1195043623
  • Python Extension version (available under the Extensions sidebar): v2021.8.1105858891
  • OS (Windows | Mac | Linux distro) and version: Ubuntu 20.04.2 LTS
  • Python and/or Anaconda version: 3.6.10
  • Type of virtual environment used (N/A | venv | virtualenv | conda | …): conda
  • Jupyter server running: Local | Remote | N/A

Expected behaviour

Saving a notebook through any means (ctrl+s, menu option, closing) saves the notebook file

Actual behaviour

File is not saved, and error generated:

_"Failed to save ‘Untitled-2’: File name file:///home/matt/Documents/Coding/Temporary/Untitled-2 is not supported by Jupyter.

Please make sure the file name matches following patterns:"_

(no patterns are listed)

Notes:

  1. Saving .ipynb using the old jupyter (i.e. opening ipynb with ‘Jupyter Notebook (custom)’ works fine.
  2. Specifying the .ipynb extension does not resolve the issue.
  3. Re-installing anaconda & vs code did not resolve the issue

Steps to reproduce:

  1. Create a new notebook
  2. Attempt to save
  3. enter any filename, with or without *.ipynb extension included

Logs

Error message generated:

"Failed to save ‘Untitled-2’: File name file:///home/matt/Documents/Coding/Temporary/Untitled-2 is not supported by Jupyter.

Please make sure the file name matches following patterns:"

Changing logging level in json settings to debug with “python.logging.level”: “debug”, the following output is generated when ctrl+shift+p creating new jupyter notebook. (No output is generated when attempting to save)

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

@ZellDD Awesome, thanks for the help! I removed the json & removed code, turns out I had installed it via snap originally, probably following this, so checked what kind of things snap keeps around and removed that too:

  • snap saved
  • snap forget 1 (there was only 1 snapshot, for code)
  • reinstalled v1.58 with sudo apt-get install code:amd64=1.58.2-1626302803 And it works fine… I was curious, so I repeated the steps (minus snapshot) and installed 1.59… Also works! So maybe the snapshot config / json file was causing grief? Though I had tried cleaning the settings.json file previously, but not sure…

I solved the problem on windows by reinstalling vs code, just make sure to delete everything before the new installation as explained here: https://debug.to/1074/how-to-uninstall-vs-code-completely

Sup, basically i had the same issue. By deleting the settings.json of my user, purging vs code and reinstalling, the problem was solved for me. I cant say the solution is to delete the settings.json file because i tried to reproduce it with the previous .json. The problem occured by updating from 1.58.2 to 1.59. Im using pop!os so this might only work for deb users:

  1. cd .config/Code/User, open directory
  2. check for settings.json, should be in there
  3. rm settings.json, deleted file
  4. sudo apt-get purge code
  5. Install vs code via pop!os shop (only 1.58.2 available 😛)
  6. Updating via .deb from vs-code website

After this process the file extension was added to the new file, which wasnt there before. I already tried to add it manually ahead of reinstalling,didnt work for me. In my experience u cant add the file extension manually, maybe i did type it in false… Correct me if im wrong 😄 . file_extension
