Error while runClient

[RaphtikAtGHG]

I made a mod that adds a custom keybind but it doesnt work:

Error:

Caused by: org.quiltmc.loader.impl.entrypoint.QuiltEntrypointException: Exception while loading entries for entrypoint 'client' provided by 'rebug'

Caused by: org.quiltmc.loader.api.LanguageAdapterException: Class io.github.concrafter20.RebugClient cannot be cast to net.fabricmc.api.ClientModInitializer!

Here is the code from RebugClient:

package io.github.concrafter20;

import io.github.concrafter20.event.KeyInputHandler;
import org.quiltmc.loader.api.ModContainer;
import org.quiltmc.qsl.base.api.entrypoint.client.ClientModInitializer;
import org.quiltmc.qsl.base.api.entrypoint.ModInitializer;

public class RebugClient implements ClientModInitializer{

	public void onInitializeClient(ModContainer mod) {
		KeyInputHandler.register();
	}

}

KeyInputHandler:

package io.github.concrafter20.event;

import com.mojang.blaze3d.platform.InputUtil;
import io.github.concrafter20.screens.RebugMenuScreen;
import net.fabricmc.fabric.api.client.keybinding.v1.KeyBindingHelper;
import net.minecraft.client.MinecraftClient;
import net.minecraft.client.option.KeyBind;
import org.lwjgl.glfw.GLFW;

public class KeyInputHandler {

	public static final String KEY_CATEGORY_REBUG = "key.category.rebug.rebug";
	public static final String KEY_OPEN_MENU = "key.rebug.open-menu";

	public static KeyBind openMenuKey;

	public static void registerKeyInputs() {
		if (openMenuKey.wasPressed()) {
			MinecraftClient.getInstance().setScreen(new RebugMenuScreen(MinecraftClient.getInstance().currentScreen));
		}
	}

	public static void register() {
		openMenuKey = KeyBindingHelper.registerKeyBinding(new KeyBind(
				KEY_OPEN_MENU,
				InputUtil.Type.KEYSYM,
				GLFW.GLFW_KEY_Z,
				KEY_CATEGORY_REBUG
		));

		registerKeyInputs();
	}
}

And here is quilt.mod.json

			{
				"id": "minecraft",

			}
		]
	},
	"mixin": "example_mod.mixins.json"
}

Any idea how i can fix this?
