Solved Need help with config

I will write a feedback plugin..

PHP:

public function onEnable() {
        $this->getServer()->getPluginManager()->registerEvents($this, $this);
        @mkdir($this->getDataFolder());
        $this->saveDefaultConfig();
        $this->reloadConfig();
    }
   
    public function onCommand(CommandSender $sender, Command $command, $label, array $args) {
        if($command->getName() === "feedback" && isset($args[0])) {
            $name = $sender->getName();
            $this->getConfig()->set("Name: ".$name);
            $this->getConfig()->set("Feedback: ".$args[0]);
            $this->getConfig()->save();
        }
    }

But I get this error:

Code:

[15:56:52] warning> RuntimeException: "yaml_parse(): end of stream reached without finding document 0" (E_WARNING) in "/src/pocketmine/utils/Config" at line 148

Does anyone know why? ._.
Thanks!

You have an empty config.yml

Yes..? Is it wrong to have an empty config? What should be in the config?

At least put these:

Code:

---
...

Otherwise, YAML will throw an exception because it found an entirely empty document that it cannot even find anything that suggests that it might be a YAML file.

Thanks! But now I get this error :/

Code:

[18:10:38] system> Enabling FeedbackPlugin v1.0.0
[18:10:38] notice> InvalidArgumentException: "Argument 1 passed to pocketmine\utils\Config::setDefaults() must be of the type array, null given, called in phar://C:/Users/allesklar/Desktop/Minecraft PE/PocketMine_Plugins/Test-Server/PocketMine-MP.phar/src/pocketmine/plugin/PluginBase.php on line 266 and defined" (E_RECOVERABLE_ERROR) in "/src/pocketmine/utils/Config" at line 419

You expect an empty array in your YAML?
Maybe you should put this:

Code:

--- []
...

This is what yaml_emit([]) would generate.

Thank you! <3
