Native VSCode editor does not work

[ebetica]

Thanks for all your amazing work on Marimo. I'm so excited to see this replace my jupyter notebooks so I can run typechecking and all the goodness of notebooks with python files :)

I'm running the Native VSCode editor for marimo==0.7.8, all I see is a blank screen that says Loading.

The web app works as expected.

Same thing happens to me on

• marimo 0.8.0
• vscode-marimo 0.4.2
• MacOS Sonoma 14.5
• VS Code 1.92.2

Here are the output logs:

@mscolnick I'm still having this issue with vscode-marimo v0.4.8.

[mscolnick]

@mentoc3000, do you see any errors in the extension logs?

[mentoc3000]

I do not. Here are my steps to reproduce:

1. Open empty directory in VS Code
2. Run command "marimio: Create new marimo notebook"
3. Name it whatever

I get that loading screen above that never resolves. My logs are below:

I am able to use the extension to launch the marimo server which I then access via the browser, though.

@mscolnick
I am facing the same issue when I attempt to "Open as VSCode Notebook".

When I attempt to "Start in marimo editor", the following message appears:
Error running command marimo-explorer.edit: fetch failed. This is likely caused by the extension that contributes marimo-explorer.edit.

My marimo version is 0.9.21

[cotucotudu]

@mscolnick I face exactly what I described in my previous comment with marimo 0.9.27 :(

[mentoc3000]

@mscolnick I propose that this issue be reopened. #41 didn't resolve the issue as far as I can tell.

[gabrielgrant]

yup, also still having this issue:

$ /home/gabriel/marimo-env/bin/python -m marimo --version
0.9.34

[mscolnick]

Does stopping and restarting the server fix this?
Can you verify the server is healthy through the Command Palette marimo: Show marimo status (and the bottom line)

[gabrielgrant]

@mscolnick marimo server seems to be running fine -- I'm able to use it through the browser

Not sure if this is actually an issue, but when I try to open the notebook, I see the following output from the marimo extension (Bottom pane > Output > Marimo):

and the following toast message:
