Hi people,
I have updated yesterday my flakes to the most recent unstable version and with that, I started getting an error.
error:
… while calling the 'head' builtin
at /nix/store/g68f5abh3xhcz8xsdlfw7wkgkkcx3nwy-source/lib/attrsets.nix:820:11:

error:
Failed assertions:
- Your system configures nixpkgs with an externally created instance.
`nixpkgs.config` options should be passed when creating the instance instead.
I saw a similar thing on another topic, but the person there was using snowfall to define their flake file.
Does anyone know what I can do to get around this issue? Thanks.
