• In vscode (Version: 1.90.1 (Universal)), when I try to export a simple Python file as a Jupyter Notebook, it fails. The Jupyter output logs show this error: 06:16:59.616 [error] listenForErrors [Error: vscode.ipynb extension not found

• I am running in a venv on a Mac and have tried installing jupyter in my venv using brew and also pip. I’ve confirmed that Jupyter is installed in my venv and when right clicking in my Jupyter code, and choosing “Export Current File as Jupyter Notebook”, it goes to a “save as” dialog box. When I hit save, I see the error message: “vscode.ipynb extension not found. View jupyter log”. The logs show the error message “Error: vscode.ipynb extension not found”

Here’s my jupyter version output from my venv
(.venv) hbh@JMBP experiments % jupyter –version

I’ve double checked that I’m using my .venv environment from the command Palette: Jupyter: Select Interpreter to start Jupyter Server
