Hello,
I am running into an error when I run the saveSVG.js example on a Ubuntu 20.04 host. The example runs OK for me in my windows machine. (both are using node 15).
me@host:~/share/github/radiation-transport-visualization/geometry-browser/node$ node saveSVG.js

You can reproduce this on a docker container as follows (I demonstrate it for node 12, but would also fail for 15, but I don't use 15 since additional dependencies are requiered):
docker run -it ubuntu:latest
apt update
apt install -y curl git
curl -sL https://deb.nodesource.com/setup_12.x | bash -
apt install -y nodejs
node --version
npm install jsroot
git clone https://github.com/root-project/jsroot.git
cd jsroot/demo/node
node makesvg.js
After installing, the error is the following:
