Best way to access this?

Hey, I want to make a command wich adds a pitch for every home a player has:

Code (Text):

Set<String> players = fc.getData().getKeys(false);
                for (String str : players) {
                    for (String homes : fc.getData().getStringList(str + ".homes.")) {
                        fc.getData().set(homes + ".Pitch", new Float(1));
                    }
                }

I'm quite bad at accessing files. But this is my file:

Code (Text):

3cfa3047-782d-3cdd-9ee9-74fc60d93cd8:
  fly: false
  god: false
  homes:
    oke:
      world: world
      X: -42.38082052154324
      Y: 69.0
      Z: 249.89942158957027
      Yaw: -22.29183
    hallo!:
      world: world
      X: -42.38082052154324
      Y: 69.0
      Z: 249.89942158957027
      Yaw: -22.29183
  vanish: false
  tptoggle: false
  frozen: false
  msgToggle: false
  banned: false
  cmdSpy: false

So I want to set the pitch to 1 for every home, Mine should be working I just dont really understand whats going wrong

 

Yes I do that, But it doesnt seem to access the homes

package me.kyllian.system32.commands;

import me.kyllian.system32.utils.FileCreator;
import me.kyllian.system32.utils.Messages;

public class RepairPlugin implements CommandExecutor {
   
    private Messages mes = new Messages();
    private FileCreator fc = FileCreator.getInstance();

    public boolean onCommand(CommandSender s, Command cmd, String commandLabel, String[] args) {
        if (cmd.getName().equalsIgnoreCase("repairplugin")) {
            if (args.length == 0) {
                if (!(s.hasPermission("system32.repairplugin"))) {
                    mes.noPermissions(s);
                    return true;
                }
                Set<String> warps = fc.getWarpData().getKeys(false);
                for (String str : warps) {
                    fc.getWarpData().set(str + ".Pitch", new Float(1));
                }
                Set<String> players = fc.getData().getKeys(false);
                for (String str : players) {
                    for (String homes : fc.getData().getConfigurationSection(str + ".homes").getKeys(true)) {
                        fc.getData().set(homes + ".Pitch", new Float(1));
                    }
                }
                Set<String> jails = fc.getJailData().getKeys(false);
                for (String str : jails) {
                    fc.getJailData().set(str + ".Pitch", new Float(1));
                }
                fc.getSpawnData().set("Pitch", new Float(1));
                fc.saveData();
                mes.pluginRepaired(s);
            } else {
                mes.tooManyArguments(s);
                return true;
            }
        }
        return true;
    }
}
 

Will fix the new Float thing.

Added configuationsection check. Now I get an NPE in that line

Code (Text):

                    for (String homes : fc.getData().getConfigurationSection(str + ".homes").getKeys(true)) {
