Bug in `notebook.redefine` when trying examples/barchart.js

[stevenweaver]

Hi,

When trying out the package (which I'm very excited about), I come across an error when I execute

node examples/barchart.js

The error message being

13:29:28 sweaver@Stevens-MacBook-Pro.local observable-prerender main node examples/barchart.js 
node:internal/process/promises:288
            triggerUncaughtException(err, true /* fromPromise */);
            ^
