flake-utils.lib.mkApp is broken with nix 2.8 about flake-utils HOT 4 CLOSED

is that fixed?

from flake-utils.

This issue is still happening when using defaultApp = flake-utils.lib.mkApp { drv = package; }; with nix-2.8 .
This seems to work though: apps.default = flake-utils.lib.mkApp { drv = package; }.

It does not seem like this issue should have been closed.

EDIT: Discovered that the problem I was describing underneath the divider, below, was because I wasn't conforming to c0e246b . After respecting that commit and moving my defaultApp value to apps.default nix run . works fine.

        apps = rec {
          go_1_18-fips = flake-utils.lib.mkApp { drv = packages.go_1_18-fips;  exePath = "/bin/go";};
          default = go_1_18-fips;
        };

I have a bunch of files in $out/bin and trying to select only one for defaultApp with exePath or name fails with the above error. It doesn't matter if I try apps.defaultApp or defaultApp.

        apps.defaultApp =  flake-utils.lib.mkApp { drv = packages.go_1_18-fips;  name = "go";};

However, the below works just fine as nix run .#go_1_18-fips

        apps.go_1_18-fips = flake-utils.lib.mkApp { drv = packages.go_1_18-fips;  name = "go";};

It's possible this has been the case for as long as nix 2.8. But, in my case

$ nix --version
nix (Nix) 2.10.3

$ cat flake.lock | grep numtide -C 10
