If your action uses extra_nix_config, like so:
- uses: cachix/install-nix-action@v14
with:
install_url: https://nixos-nix-install-tests.cachix.org/serve/ipa0c64h689jb4ys6hxsky2r8xpld0hv/install
install_options: '--tarball-url-prefix https://nixos-nix-install-tests.cachix.org/serve'
extra_nix_config: experimental-features = nix-command flakes
It will only work in a daemon install. For the single-user mode, such as when using ACT, the config ends up empty.
To reproduce, create this demo.yml:
name: Demo
