nix flake show: name attribute that must be a derivation

Browse source 
I would run `nix flake show` on a flake than hit:

===
        ├───ihaskell: package 'ihaskell-wrapper'
        ├───ihaskell-96: package 'ihaskell-wrapper'
        ├───ihaskell-96-dev: package 'ghc-shell-for-ihaskell-0.10.4.0'
error: expected a derivation
===
and it is not obvious what package is the culprit here since nix stops
rightaway.
