javascript - 无法读取未定义和未处理的 promise 拒绝的属性 'catch'

Question

有人知道如何修复这些错误吗，因为我不知道，我尝试了几种方法，但没有任何效果。顺便说一句，我是一个初学者。

client.on("guildMemberAdd", member => {
    try {
        member.send(`Hello ${member}, welcome to the PotatoHost Server! 
I want to help you and so my question is: Do you want to buy a server or do you need more informations first? \n
A: I want to buy a server
B: I need more informations first \n
Please react to this message with A or B.`)
        .then(function (message) {
            message.react("🇦")
            message.react("🇧")     
            message.awaitReactions((reaction, user) => user.id == message.author.id && (reaction.emoji.name == '🇦' || reaction.emoji.name == '🇧'),
                { max: 1}).then(collected => {
                    if (collected.first().emoji.name == '🇦') {
                        message.send.catch(err => console.log(err))('Ok, so you want to buy a server. Let me recommend you to visit <#699374469977735208>.');
                        client.destroy();
                    }
                    else
                        message.send.catch(err => console.log(err))('Ok, so you need more informations first. Let me recommend you to visit <#699374469977735208>.');
                })
        });
    }catch (err) {
         console.log(err)
    }
})

错误:

correct syntax是:

message.channel.send('MESSAGE').catch(console.error);
