Vscode-jupyter: Jupyter Notebook editor not opening

[constant5]

Issue Type: Bug

Not sure what changed but after using Jupyter Notebook for some time in VS code the notebook editor stopped opening. I'm not sure how to reproduce this issue but now I can't use notebooks in VS Code.

I confirmed it is is not working locally or on a remote session.

VS Code version: Code - Insiders 1.47.0-insider (0913b1aa43191d8af0ccb4a133d9a8d7c1a81d69, 2020-06-23T09:03:35.861Z)

@constant5 thanks for reporting and sorry about the issue. I see that you are on vscode - insiders. There is currently a general issue with opening webviews on insiders. If you get just a file tab with a totally blank screen when you open up a notebook editor then you might be running into this issue.

When this happens could you run the command "Developer: Open webview developer tools" and see if there are any errors in the console section?

@IanMatthewHuff I ran into the same issue as well on the 1.47.0-insider build and extension version: 2020.6.89148.

The notebook does not seem to load, just gives a blank screen, strangely the scroll bars seem to load up on the sides.
I did check the console on the webview developer tools. Here's what I found.

Failed to load resource: net::ERR_UNKNOWN_URL_SCHEME require.js:1 
Failed to load resource: net::ERR_UNKNOWN_URL_SCHEME ipywidgets.js:1
Failed to load resource: net::ERR_UNKNOWN_URL_SCHEME monaco.bundle.js:1 
Failed to load resource: net::ERR_UNKNOWN_URL_SCHEME commons.initial.bundle.js:1 
Failed to load resource: net::ERR_UNKNOWN_URL_SCHEME nativeEditor.js:1

Hope this helps.

Looks like there was a VSCode issue affecting all webviews (which our editor is) looks like it was resolved in a recent update, so the next insiders build should clear this up.

The latest update to 1.47.0 resolved the issue. Thanks, I eally enjoy using Jupyter Notebooks with VS Code!
