Issue with expand env shell variables

[webhive]

I am not familiar with nix, so not sure about this is an error or my misconfiguration.
Anyway got an error after this code in my config

  launchd.user.envVariables = {
        PATH = config.environment.systemPath;
  };

It cause this error

  launchctl setenv PATH '$HOME/.nix-profile/bin:/etc/profiles/per-user/$USER/bin:/run/current-system/sw/bin:/nix/var/nix/profiles/default/bin:/usr/local/bin:/usr/bin:/usr/sbin:/bin:/sbin'
                        ^-- SC2016 (info): Expressions don't expand in single quotes, use double quotes for that.

After some investigation I got this.

Here we can see '${value}' in single quotes

nix-darwin/modules/system/launchd.nix

Lines 14 to 16 in 698a62c

	launchdVariables = mapAttrsToList (name: value: ''
	launchctl setenv ${name} '${value}'
	'');

It generating the following code on my system

  In /nix/store/xzsjqwz6l61z1pmwbiq00ikmlfgyy7q5-darwin-system-24.05.20241106.c128e44+darwin5.edabc79/activate-user line 375:
  launchctl setenv PATH '$HOME/.nix-profile/bin:/etc/profiles/per-user/$USER/bin:/run/current-system/sw/bin:/nix/var/nix/profiles/default/bin:/usr/local/bin:/usr/bin:/usr/sbin:/bin:/sbin'
                        ^-- SC2016 (info): Expressions don't expand in single quotes, use double quotes for that.

So after all here is a question - is this an error and there should be double quotes or I got it wring.

For anyone else struggling with this, I realized in my case this was to do with the following configuration:

  # Path fix for GUI applications.
  launchd.user.envVariables.PATH = config.environment.systemPath;

After commenting this line out, everything appears to have been built successfully.
