TypeError [ERR_INVALID_ARG_TYPE]：“侦听器”参数必须是函数类型。收到未定义

Question

在对象处。 （C：\ Users \ Hades \ Downloads \ Jaxxy \ src \ bot.js：51：8）

我指定命令的代码是

client.on('guildMemberAdd'), member => {
  const channel = member.guild.channels.cache.find(channel=> channel.name === "welcome");
  if(!channel) return;
  channel.send(`Welcome to Hades's Tavern,$(member), make sure to read the rules in #rules!`)

};

我正在使用discord.js v12！ 有任何线索吗？

Answer 1

右括号必须在箭头函数的主体之后：

client.on('guildMemberAdd', member => {
    const channel = member.guild.channels.cache.find(channel => channel.name === "welcome");
    if (!channel) return;
    channel.send(`Welcome to Hades's Tavern,$(member), make sure to read the rules in #rules!`)

});
