@jsjoeio This is the bug report you asked for in issue https://github.com/cdr/code-server/issues/3776.

I found this thread after hours of searching on the Internet for the enable-proposed-api problem. And it took another hour to read and understand.

Here is what worked for me finally (@jsjoeio’s solution https://github.com/coder/code-server/issues/3782#issuecomment-996202105) :

1. Install v4.0.0 prelease code-server.
2. Install the latest python extension from the sidebar (and the Jupyter extension will get installed automatically). In my case it was Python v2021.12.1559732655 (and Jupyter v2021.11.1001552333).
3. Add the following snippet to ~/.local/share/code-server/extensions/ms-toolsai.jupyter-<version>/package.json

"enabledApiProposals": [
        "notebookConcatTextDocument",
        "notebookControllerKind",
        "notebookDebugOptions",
        "notebookDeprecated",
        "notebookEditor",
        "notebookEditorDecorationType",
        "notebookEditorEdit",
        "notebookMessaging",
        "notebookMime",
        "notebookCellExecutionState",
        "portsAttributes",
        "textDocumentNotebook",
        "quickPickSortByLabel"
    ],

Restart code-server (without any --enabled-proposed-api arguments)

So far I figured out at least two issues that are rather strange:

1. Running NBs does not work: (According to browser console File not found)

1. Changing Python Interpreter does not work. "Failed to set 'pythonPath'. Error: Unable to write to Folder Settings because no resource is provided."

Okay seems like I figured out in which situation it works and in which not:

If I start code-server using code-server . (notice the dot for the current directory) and visit it using the browser afterwards:

• http://127.0.0.1:8080/vscode/ does not work
• http://127.0.0.1:8080/vscode/?folder=%2Fhome%2Fjovyan works perfect.

Maybe that helps?
