Build of stack project failing

[m-col]

Hi there. I am trying to build a small stack project (here, 'static' branch) following the example project. Unfortunately when I try to build, I get this error:

...
+ cabal2nix --subpath . --system x86_64-linux --compiler ghc-9.0.1 cabal://zstd-0.1.3.0

stack2nix: post-process: cannot replace name binding Bind (Identifier "lua") (Path [Identifier "pkgs",Identifier "lua"]) by Bind (Identifier "lua5_3") (Path [Identifier "pkgs",Identifier "lua5_3"]) because it's not found in set fromList []
CallStack (from HasCallStack):

I'm very new to nix so perhaps there is an obvious, but any advice would be appreciated! Do you know if this could be a project with my default.nix, or the project?
