Flake option is a path but expects a set later on

[b-m-f]

The flake option is expected to be a path, but when passing a path I get the following error:

error: value is a path while a set was expected

I have tried #149, which makes it work as expected for me.

This is the config

    dev-microvm = {
      flake = "git+https://my-git/b-m-f/dev-microvm";
      # Specify from where to let `microvm -u` update later on
      updateFlake = "git+https://my-git/b-m-f/dev-microvm";
    };
