Discord.js Slash Command报错：ExpectedConstraintError修复求助

在使用Discord.js开发Slash Command时，遇到如下报错：

ExpectedConstraintError: Invalid string format

相关代码 #

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

module.exports = {
    data: new SlashCommandBuilder()
        .setName('Ping')
        .setDescription('Return my ping'),
    async execute(interaction, client) {
        const message = await interaction.deferReply({
            fetchReply : true
        });

        const newMessage = `API Latency: ${client.ws.ping}\nClient Ping: ${message.createdTimestamp - interaction.createdTimestamp}`
        await interaction.editReply({
            content: newMessage
        });

    }
}

找不到解决办法，相关讨论帖也无法解决问题，求修复方案。

修复方案 #

问题根源在于Discord的Slash Command名称必须全小写，且只能包含小写字母、数字、下划线和连字符，不能有大写字母。你的代码里.setName('Ping')用了大写首字母，不符合规则。

修改后的代码：

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

module.exports = {
    data: new SlashCommandBuilder()
        .setName('ping') // 改为全小写
        .setDescription('Return my ping'),
    async execute(interaction, client) {
        const message = await interaction.deferReply({
            fetchReply : true
        });

        const newMessage = `API Latency: ${client.ws.ping}\nClient Ping: ${message.createdTimestamp - interaction.createdTimestamp}`
        await interaction.editReply({
            content: newMessage
        });

    }
}

修改后重新部署命令即可解决该错误。
