Discord.js执行Ping命令时显示The application did not respond且无代码报错

刚学习discord.js基础知识，测试Ping斜杠命令时，Discord界面显示The application did not respond，但代码运行过程中未出现任何报错信息。

主代码 #

const fs = require('node:fs');
const path = require('node:path');

const { Client, Collection, Events, GatewayIntentBits } = require('discord.js');
const { token } = require('./config.json');

const client = new Client({ intents: [GatewayIntentBits.Guilds] });

client.commands = new Collection();

const foldersPath = path.join(__dirname, 'commands');
const commandFolders = fs.readdirSync(foldersPath);

for (const folder of commandFolders) {
    const commandsPath = path.join(foldersPath, folder);
    const commandFiles = fs.readdirSync(commandsPath).filter(file => file.endsWith('.js'));
    for (const file of commandFiles) {
        const filePath = path.join(commandsPath, file);
        const command = require(filePath);
        if ('data' in command && 'execute' in command) {
            client.commands.set(command.data.name, command);
        } else {
            console.log(`[WARNING] The command at ${filePath} is missing a required "data" or "execute" property.`);
        }
    }
}

client.on(Events.InteractionCreate, interaction => {
    if (!interaction.isChatInputCommand()) return;
    const command = interaction.client.commands.get(interaction.commandName);

    if (!command) {
        console.error(`No command matching ${interaction.commandName} was found.`);
        return;
    }

    console.log(interaction);
});

client.once(Events.ClientReady, readyClient => {
    console.log(`Ready! Logged in as ${readyClient.user.tag}`);
});

client.login(token);

ping.js代码 #

const { SlashCommandBuilder } = require('discord.js');

module.exports = {
    data: new SlashCommandBuilder()
        .setName('ping')
        .setDescription('Replies with Pong!'),
    async execute(interaction) {
        await interaction.reply('Pong!');
    },
};

问题原因及修复 #

问题出在InteractionCreate事件的处理逻辑中：成功匹配到命令后，仅打印了interaction对象，没有调用命令的execute方法，导致Discord的交互请求未收到任何回复，从而触发“The application did not respond”提示。

修改InteractionCreate事件处理代码，添加execute调用，并加入错误捕获避免程序崩溃：

client.on(Events.InteractionCreate, async interaction => {
    if (!interaction.isChatInputCommand()) return;
    const command = interaction.client.commands.get(interaction.commandName);

    if (!command) {
        console.error(`No command matching ${interaction.commandName} was found.`);
        return;
    }

    try {
        await command.execute(interaction);
    } catch (error) {
        console.error(error);
        if (interaction.replied || interaction.deferred) {
            await interaction.followUp({ content: '执行命令时出现错误！', ephemeral: true });
        } else {
            await interaction.reply({ content: '执行命令时出现错误！', ephemeral: true });
        }
    }
});

修改后，调用/ping命令时，会执行ping.js中的execute方法，回复“Pong!”，Discord界面就不会再显示无响应提示。
