Error: Failed to get shell by ID...

[abstractalgo]

I'm trying to run this example app: https://github.com/abstractalgo/webcontainer-github
It fetches an example React app repo from Github and tries to run it within Nodebox.

The example runs well with WebContainers, but Nodeboox simply throws:

Error: Failed to get shell by ID "clinlnn6t0000039oe41a5r3y"
    at index.mjs:949:13

I am clueless even what to try. I've tested this with the basic Node example for Nodebox and it works, but without any information on what goes wrong with this exact setup I am not sure what to try even.
