How do I install nixopsUnstable in NixOS 22.11

I have an up-to date NixOS 22.11 installation. When I try to install it, I get an error saying that ‘python3.10-certifi-2022.9.24’ is insecure. Upstream seems to be using 2022.12.7. So Why can’t I install it?

    (self: super: {
      nixops_unstable = super.nixops_unstable.withPlugins
        (ps: [ ps.nixops-encrypted-links ps.nixopsvbox ps.nixops-virtd ]);

Disabling the plugins which depend on vulnerable stuff works.
