foxy: Install/update ends with npm error: "invalid version dev-master"

This project looks great, and I’m really excited about the prospect of finally being able to manage the front-end dependencies of our Composer packages!

As of yet, I haven’t had any luck trying it out though - every composer install or composer update ends with an npm error.

Here’s the (verbose) output:

I am just trying it out, so for now, I’ve manually listed two packages that have package files via configuration in my project’s composer.json:

    "config": {
        "foxy": {
            "enable-packages": {
                "kodus/media": true,
                "kodus/media-admin": true
            }
        }
    }

Both of these packages are on unable dev-branches, both named 1.0.0.

The package.json files in those two packages both list some "dependencies" for some npm packages.

If understand correctly, the idea is Foxy will aggregate these to a collective package.json for the project containing all the npm-dependencies of those two packages?

Any idea what I’m doing wrong?
