Websocket Version Problem

[IsaacTheKind]

I tried to set up Calamity on Nix and couldn't. I got an error like this:

error:
       … while calling the 'derivationStrict' builtin

       error: Package ‘calamity-0.11.0.0’ in /nix/store/63lvc59rjz075kb1f11xww2x2xqpw1pn-source/pkgs/development/haskell-modules/hackage-packages.nix:60187 is marked as broken, refusing to evaluate.

       a) To temporarily allow broken packages, you can use an environment variable
          for a single invocation of the nix tools.

            $ export NIXPKGS_ALLOW_BROKEN=1

          Note: When using `nix shell`, `nix build`, `nix develop`, etc with a flake,
                then pass `--impure` in order to allow use of environment variables.

       b) For `nixos-rebuild` you can set
         { nixpkgs.config.allowBroken = true; }
       in configuration.nix to override this.

       c) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
         { allowBroken = true; }
       to ~/.config/nixpkgs/config.nix.

I asked in the Haskell Discord server and they told me the fix is to submit a PR to you all to fix the versioning on websockets. I don't know how accurate any of that is, I'm just a noob. But it would be awesome if this were resolved so I could work on a Calamity project in NixOS.
