“ TypeError：无法读取null的属性'ban'

Question

我最近在制作一个自动审核机器人。我确定如果该人有30条警告，该人将被禁止。但是它向我显示了一个错误。我尝试自己修复它，但不知道问题出在哪里。这是我使用的代码：

if (warns.warns.length === 30 && message.member.bannable) {
 embed.addField(
  `⛔ ${message.author.tag} has reached 30 warnings.`,
  `**${message.author} has been banned permanently.**`,
  true
 );
 setTimeout(function() {
  message.member
   .send(banemb)
   .then((message) => message.member.ban({ reason: '30 warnings' }));
 }, 1000);
}

这是我得到的错误：

{
  "stack": "TypeError: Cannot read property 'ban' of null
at /app/app.js:157:51
    at processTicksAndRejections (internal/process/task_queues.js:88:5)"
}

Answer 1

将.then(message =>更改为.then(msg =>

因为您覆盖了消息变量，所以新的message变量为null

setTimeout(function() {
 message.member
  .send(banemb)
  .then((msg) => message.member.ban({ reason: '30 warnings' }));
}, 1000);
