升级discord.js v14后出现DiscordAPIError[50035]错误求助

我下载了discord.js v14（非最新版本），运行时遇到DiscordAPIError[50035]错误。该功能在v13.1.0版本中正常工作，但无法定位问题原因。错误提示为无效表单体，具体是"CHAT_INPUT"、"USER"、"STRING"等值不是整数，错误指向代码await guild.commands.set(slashcmds);。完整错误栈如下：

DiscordAPIError[50035]: Invalid Form Body
0.type[NUMBER_TYPE_COERCE]: Value "CHAT_INPUT" is not int.
3.options[0].type[NUMBER_TYPE_COERCE]: Value "USER" is not int.
3.options[1].type[NUMBER_TYPE_COERCE]: Value "STRING" is not int.
4.options[0].type[NUMBER_TYPE_COERCE]: Value "USER" is not int.
4.options[1].type[NUMBER_TYPE_COERCE]: Value "STRING" is not int.

问题原因 #

discord.js v14起，命令类型和选项类型不再支持字符串字面量，必须使用官方提供的枚举值（整数类型），而v13版本允许使用字符串，这是版本升级后报错的核心原因。

修复步骤 #

1. 导入枚举类型
   在代码顶部引入discord.js中的对应枚举：

const { ApplicationCommandType, ApplicationCommandOptionType } = require('discord.js');

2. 替换命令与选项的type字段
   将所有字符串类型替换为枚举值：

• 把type: "CHAT_INPUT"替换为type: ApplicationCommandType.ChatInput
• 把选项中的type: "USER"替换为type: ApplicationCommandOptionType.User
• 把选项中的type: "STRING"替换为type: ApplicationCommandOptionType.String

3. 示例对比
   修改前的命令定义：

const slashcmds = [
  {
    name: 'example',
    type: "CHAT_INPUT",
    description: '示例命令',
    options: [
      {
        name: 'target',
        type: "USER",
        description: '目标用户',
        required: true
      },
      {
        name: 'content',
        type: "STRING",
        description: '输入内容',
        required: true
      }
    ]
  }
];

修改后的命令定义：

const slashcmds = [
  {
    name: 'example',
    type: ApplicationCommandType.ChatInput,
    description: '示例命令',
    options: [
      {
        name: 'target',
        type: ApplicationCommandOptionType.User,
        description: '目标用户',
        required: true
      },
      {
        name: 'content',
        type: ApplicationCommandOptionType.String,
        description: '输入内容',
        required: true
      }
    ]
  }
];

完成以上修改后，重新运行代码即可解决该错误。
