如何处理无效数字和.catch()

Question

我试图修复此代码，但失败了这是一个向成员发送消息的代码当我选择任何号码时，它会发送一个无效的号码，这个错误就会出现在我面前

我试着修复它，但失败了。如果有任何帮助，我将不胜感激。大约一个月前，代码运行良好，但现在已经停止。我认为这与更新Discord.js 有关

client.on('message ', async (message) => {
if (!message.guild || message.author.bot) return;
if (!message.content.startsWith(prefix)) return;
if (message.content.startsWith(`${prefix}bc`)) {
if (!message.member.hasPermission('ADMINISTRATOR'))
return message.reply('You dont have Permissions.');
if (message.guild.interval)
return message.reply(
'**Another broadcast is running, please wait for it to finish ** '
);
const args = message.content.split(' ').slice(1).join(' ');
if (!args)
return message.reply(
'**Please send a message after the command to send it**'
);
message.channel
.send(
'>>> **[1] All membersn[2] Connected Membersn[3]Special ranksn[0] Cancel**'
)
.then((m) => {
message.channel
.awaitMessages((msg) => msg.author.id === message.author.id, {
max: 1,
time: 1000 * 60 * 2,
errors: ['time'],
})
.then(async (c) => {
var members = null;
if (c.first().content === '1') {
members = message.guild.members.array();
c.first().delete();
m.delete();
}
if (c.first().content === '2') {
members = message.guild.members

Answer 1

如果您使用Discord。Js 12，你必须使用缓存。所以message.guild.roles.cache.find()

文档

Answer 2

discord.jsv12及更高版本使用Managers，因此必须通过cache属性。

// change
const role = message.guild.roles.find(
(role) => role.name === c.first().content
);
// to
const role = message.guild.roles.cache.find(
(role) => role.name === c.first().content
);

// and change
members = message.guild.roles.get(roleID).members.array();
// to
members = message.guild.roles.cache.get(roleID).members.array();
