Hi, I came across this project and was eager to try it. It looks very promising.
I used the instructions given in the README.md to install helix-notes on my NixOS 26.05 machine. I added the input to flake.nix and added (helix-notes.packages.${pkgs.stdenv.hostPlatform.system}.default) into the list of packages.
When I then try to rebuild my NixOS configuration, I get the following error:
error: hash mismatch in fixed-output derivation '/nix/store/lzi9xywj5n5b8fspgvpywyr3d1qa7a7n-helixnotes-1.3.1-vendor-staging.drv':
