Error rendering output item using 'vscode.builtin-renderer'

[kevinyuan]

Dear developer,

I am using Jupyter Extension in vscode to run the roboquant, however error occurs when any plotting functions is called, e.g. PerformanceChart.

Could you help to check how to resolve this issue ?

After I deploy the roboquant locally, I can see the error in more detail:

Looks like there is a space in the example when creating the feed.

I ran into the same problem.

The code works fine when used inside a jupyter notebook, so I guess it's a limitation of Visual Studio Code?

[jbaron]

Not sure that VS Code fully supports Kotlin notebooks. If it cannot resolve feed, it seems more that the state in the first cell is not available at all in the next cell.

Does other (plain) Kotlin code run fine?

[littleant]

I'm not sure about the exact exception, just the "Cannot read properties of null (reading 'removeChild')" error.

It doesn't matter if the feed is in the same cell or not.
