Fail to install uppy and faulty composer cache

[Hanmac]

composer require "npm-asset/uppy:5.1.1" --dry-run (5.1.1 version is important)

depends on this:
https://asset-packagist.org/package/npm-asset/uppy--core

adds this to composer cache:
https://cdn.asset-packagist.org/p/npm-asset/uppy--core/1d22f2bb9e71c6e9486208c51dbf8282e5af93f5bae537e0efb898fb45fb8910.json

Which has this line:

          "npm-asset/uppy-example--dev": "file:examples/dev",

Which causes this Error:

Could not parse version constraint file:examples/dev: Invalid version string "file:examples/dev"

that infects the composer cache
