Node.js v20.15.0

Is there perhaps a nodejs version constraint which is not specified in the package.json?

Is that project still valid?

(Also, the apache/beam-starter-typescript Github project does not have issues enabled, so I assume this should get eported here)

fwiw, I tried with nodejs 18 and 16 with the same result.

Also, fwiw, I was able to set up blank nodejs tyepscript project, install apache-beam, and run trivial examples (nodejs 20.15.0). So it seems there's just something with the setup of this starter project.
