Update for anyone who runs into this later: the error only appears with the latest version of Node, using node:16 as the base image allows the script to run successfully.

@saegl5 commented on GitHub (Oct 21, 2022):

just to chime in, in case anyone else encounters this error but doesn't use docker...

I encountered the same error ("Not implemented: HTMLCanvasElement.prototype.getContext") using the Canonical snap: sudo snap install node --classic
solution for me was to download and install node.js 16 directly from https://nodejs.org/en/

sudo snap install node --channel=18/stable --classic didn't work, either
maybe the snaps don't work because of sandboxing...
