error: attribute 'hasStorePathPrefix' missing

sops-nix is failing, I'm not sure why.
this is the full error:

      … while calling the 'head' builtin

This is how my sops-nix config in configuration.nix looks like:

   sops.defaultSopsFile = ../secrets/secrets.yaml;
  sops.defaultSopsFormat = "yaml";

  sops.age.keyFile = "/home/bwkam/.config/sops/age/keys.txt";
  sops.secrets.github = { };

Updating nixpkgs fixed it
