"command-not-found itself is not enabled" error prevents building

[volkswagenfeature]

Adding flake-programs-sqlite on line 70 of my system config fails with the error message below. I am on NixOS 24.05, and using fish as my shell. What am I doing wrong?

error:

I can see that you are also using nix-index - please check if you have programs.command-not-found.enable = false; (as suggested in the nix-index readme) in your config. If so, re-enable it as requested by the error message.
