Testing #14200

After using same steps, but on vsc insiders desktop, win64, was able to connect to the existing jupyter serverproperly and execute code.

Steps Taken:

  • go to insiders.vscode.dev
  • open directory, and create newfile.ipynb
  • make sure I have jupyter pre-release installed.
  • in powershell, navigate to directory
  • activate venv
  • run python -m jupyter lab --NotebookApp.allow_origin='*'
  • copy URL given into new tab
    • jupyter lab opens as expected, can run cells and execute code in notebook, verified an active kernel.
  • return to insiders.vscode.dev
    • open notebook created earlier
    • click select kernel
    • click 'Existing Jupyter Server...'
    • 🐛 Paste URL copied from terminal (the same that was confirmed to work in the browser already), get 404'd
