How to setup buildbot credentials

Help
1

I was not able to fix my hydra configuration. So I am trying Buildbot instead.
But now I am struggling in configuring the credentials.
I get the following SystemD error:

× buildbot-master.service - Buildbot Continuous Integration Server.
     Loaded: loaded (/etc/systemd/system/buildbot-master.service; enabled; preset: ignored)
     Active: failed (Result: exit-code) since Wed 2024-12-04 16:41:04 CET; 3s ago

The error is propably in the way i configured the workersFile:

{ inputs, config, ... }:

let
  hostName = config.networking.hostName;
  cfg = config.sops;
in {
  imports = [ inputs.sops-nix.nixosModules.sops ];

  sops = {
    secrets = {
      codeberg-token = {
        owner = "buildbot";
        group = "buildbot";
      };
      cb-buildbot-secret = {
        owner = "buildbot";
        group = "buildbot";
      };
      buildbot-webhook = {
        owner = "buildbot";
        group = "buildbot";
      };
      hetzbox-buildbot-worker-password = {
        owner = "buildbot-worker";
        group = "buildbot-worker";
      };
    };

    templates = {
      "buildbot-workers.json" =
      let
        masterCfg = config.services.buildbot-nix.master;
        backendPort =
          if (masterCfg.accessMode ? "fullyPrivate") then
            masterCfg.accessMode.fullyPrivate.port
          else
            config.services.buildbot-master.port;
      in {
        content = ''
          [
            {
              "name": "${hostName}",
              "password": "${cfg.placeholder.hetzbox-buildbot-worker-password}",
              "host": "${hostName}",
              "port": ${(toString backendPort)}
            }
          ]
        '';
        owner = "buildbot";
        group = "buildbot";
      };
    };
  };
}

Help is very apreciated

Nvm I had no secrets available because I set the owner of a sops.secret to a non existant user
