Keylogger doesn't work properly when in chat box.

[charlie512]

I have a keylogger code as following:

package com.key_logger_mod;

import com.google.gson.Gson;
import com.google.gson.GsonBuilder;
import net.minecraftforge.api.distmarker.Dist;
import net.minecraftforge.client.event.InputEvent;
import net.minecraftforge.eventbus.api.SubscribeEvent;
import net.minecraftforge.fml.common.Mod;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
import net.minecraft.client.Minecraft;
import org.lwjgl.glfw.GLFW;

import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import java.nio.file.StandardOpenOption;
import java.util.HashMap;
import java.util.Map;

@Mod.EventBusSubscriber(modid = "key_logger_mod", bus = Mod.EventBusSubscriber.Bus.FORGE, value = Dist.CLIENT)
public class KeyboardLogger {
    private static final Logger LOGGER = LogManager.getLogger();
    private static final Gson gson = new GsonBuilder().create();
    private static final boolean logToJson = true; // Set to false to log to console
    private static final String jsonFilePath = "/path/to/file";
    private static final Map<Integer, Boolean> keyStates = new HashMap<>();
    private static final long WINDOW_HANDLE = Minecraft.getInstance().getWindow().getWindow(); // Get the window handle

    static {
        initializeLogFile();
    }

    private static void initializeLogFile() {
        Path path = Paths.get(jsonFilePath);
        try {
            Files.write(path, "[".getBytes(), StandardOpenOption.CREATE, StandardOpenOption.TRUNCATE_EXISTING);
        } catch (IOException e) {
            LOGGER.error("Failed to initialize JSON file", e);
        }
    }

    @SubscribeEvent
    public static void onKeyInput(InputEvent.Key event) {
        if (Minecraft.getInstance().level == null) return; // Only log if the player is in the game world

        long timestamp = System.currentTimeMillis();
        int key = event.getKey();
        int action = event.getAction();
        int mods = event.getModifiers();

        synchronized (keyStates) {
            if (action == GLFW.GLFW_PRESS) {
                if (!keyStates.getOrDefault(key, false)) {
                    keyStates.put(key, true);
                    logKeyAction(timestamp, key, "PRESS");
                }
            } else if (action == GLFW.GLFW_RELEASE) {
                if (keyStates.getOrDefault(key, false)) {
                    keyStates.put(key, false);
                    logKeyAction(timestamp, key, "RELEASE");
                }
            }
        }
    }

    private static void logKeyAction(long timestamp, int key, String action) {
        KeyboardData keyboardData = new KeyboardData(timestamp, key, action);
        if (logToJson) {
            try {
                String jsonData = gson.toJson(keyboardData) + ",";
                Files.writeString(Paths.get(jsonFilePath), jsonData + System.lineSeparator(), StandardOpenOption.CREATE, StandardOpenOption.APPEND);
            } catch (IOException e) {
                LOGGER.error("Failed to write keyboard event to JSON file", e);
            }
        } else {
            LOGGER.info("Timestamp: {}, Key: {}, Action: {}", timestamp, key, action);
        }
    }

    static class KeyboardData {
        long timestamp;
        int key;
        String action;

        KeyboardData(long timestamp, int key, String action) {
            this.timestamp = timestamp;
            this.key = key;
            this.action = action;
        }
    }
}

It works fine when players play normally, every key is registered. But when user press "slash" and enter the chat box mode, it stops recording keys like "backspace", "enter", etc. But still registering characters and number keys. Why is this happening?
