Describe the bug

A clear and concise description of what the bug is.

If you have a problem with a specific package or NixOS,
you probably want to file an issue at https://github.com/NixOS/nixpkgs/issues.

Steps To Reproduce

nix run --impure --expr '{pkgs ? import <nixpkgs> {}}: pkgs.hello'

Result

error: attribute 'type' does not exist

Expected behavior

I expect nix run to evaluate the function with default agrurments.

nix-env --version output

nix-env (Nix) 2.4pre20210922_bcd73eb

Additional context

My actual use case involves passing -f /path/to/command.nix. nix shell has the expected behavior.

This is still not fixed.

And the error message is incredibly unhelpful.

Agree, this is a much needed user experience improvement imo.
