解决方案 #

错误根源是Slash命令名称不符合Discord的规则：命令名必须全小写，仅允许包含小写字母、数字、下划线_和连字符-，不能出现大写字母。

你的ping.js中把命令名设为了"Ping"（首字母大写），违反了格式限制。修改成全小写的"ping"即可解决问题，修改后的ping.js代码如下：

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

module.exports = {
  data: new SlashCommandBuilder()
    .setName("ping")
    .setDescription("Replies with pong"),
  async execute(interaction) {
    console.log(interaction);
    await interaction.reply("pong");
  },
};
