Thanks for filing this issue and testing the latest changes, and sorry you are running into this issue.
Please could you confirm the fact that this works when you are NOT using a multi-root workspace folder (i.e. that it works when opening a single folder in vscode). thanks |

No. This issue has only occurred for me when working with a single folder workspace at |

Sorry, but I still don’t understand that |

Sure. Here's a gif that might help. Also, I missed it before, but even the workspace that I thought was working has some issues. At the end of the gif, you can see the KeyErrors pop up when I hover over the image.

The widget also partially works (but with KeyErrors) if I just open my home directory as a single root project (which also includes the sample notebook from above). I think it has to do with the

@matthai An easy workaround until there is a fix is to add the "files.exclude": {

What happened?
Recently, support for ipywidgets 8 was added with #8552. After updating to the latest vscode-insiders and the pre-release versions of the Jupyter extension and notebook renderers, all my widgets load properly except for the matplotlib widget. This happens on two different remote machines running Ubuntu Server 22.04.1 LTS. When attempting to plot with
%matplotlib widgetenabled, I get a window that says, "Click to show javascript error." Clicking this shows the following:Typically, I work within single folder workspaces for my projects. For this project, it's located under
~/projects/{my-project}. Interestingly, if I add my home directory (~/) to the project making it a multi-root workspace, the error goes away. I'm guessing this means there is an issue with getting the proper path for the widget when it's not part of the workspace.VS Code Version
