Updated my system this morning on MacOS and since then have been unable to use Nix to build anything.
Attempted to rollback the profile to generations before the update but I am still getting this error.
Has the new version changed something in the Nix store that is making breaking the old versions?
EDIT:
So rolling back the system generation on MacOS using:
nix-env --list-generations --profile /nix/var/nix/profiles/system
has rolled back most things but for some reason the Nix daemon is still on 2.21.0:
❯ pgrep -fl nix-daemon <region:eu-west-2>
1084 /nix/store/55na9m4x162ai94y8y4d2jzs7z0hck30-nix-2.21.0/bin/nix-daemon
16256 /nix/store/55na9m4x162ai94y8y4d2jzs7z0hck30-nix-2.21.0/bin/nix-daemon
so it seems that the nix-daemon isn't using the system profile... digging further....
Located the nix-daemon service file at: /Library/LaunchDaemons/org.nixos.nix-daemon.plist.
Doesn't seem to be managed by the Nix store so that explains why it hasn't been rolled back.
It has the content:

</plist>Going to attempt manually rewrite it to a Nix nix-daemon path from an older version.
UPDATE:
So after looking at the nix packages in the nix store I found this: /nix/store/xddsxyp60qq5jmdxb9rkwbvxzxa4lhar-nix-2.19.3/Library/LaunchDaemons/org.nixos.nix-daemon.plist
Which contains a better way to manage the nix-daemon version (wonder why my service was using the wrong version?):
<?xml version="1.0" encoding="UTF-8"?>

</plist>UPDATE:
After rewriting the service file and rebooting (probably could have just restarted the service) the nix-daemon version is now in sync with the client and I am no longer getting this issue. However on further inspection the default profile that the service file from the nix derivation is using nix-daemon 2.17.0. I am going to rewrite it once more to use the system profile so that it stays in sync with the rest of the system.
UPDATE:
Have rewritten it and everything is in sync as expected now. The final version of the services file I ended up with is:
<?xml version="1.0" encoding="UTF-8"?>

</plist>UPDATE:
It seems for me that Nix 2.21.0 is just broken. Even when the daemon and the client are both in sync:
❯ nix build '#.packages.aarch64-darwin.app' <region:eu-west-2>
warning: Git tree '/Users/ajenkins/git/myproj' is dirty

Going to roll back to a previous version of Nix and pin until this issue is resolved.

I'm having the same issue as @alisonjenkins, my daemon and CLI are both on 2.21.0:
❯ nix-shell -p nix-info --run "nix-info -m"
- system: `"x86_64-linux"`
- host os: `Linux 6.7.9, NixOS, 24.05 (Uakari), 24.05.20240313.9dce028`
- multi-user?: `yes`
- sandbox: `yes`
- version: `nix-env (Nix) 2.21.0`
- nixpkgs: `/nix/store/c02aa9kbhwm2az5vg2m6vvwzrrj3qdqs-xgviqbk8bf1w47kfyqakqhq92a1v3n8v-source`I have a few SSH remote builders configured; my /nix/store is on a dedicated ZFS dataset; I'm building flakes with nix build .#xyz.
EDIT:
It seems like the SSH remote builders either cause or amplify the cause of the issue; adding --builders "" to my command to reset the list of remote builders lets it succeed.
