为什么给我这个错误？如何定义表情符号？ IT人员应该只检查反应是否与该表情符号有关。

.then(function (message, reaction) {
                message.react("?")
                message.react("?")

                const filter = (reaction, user) => {
                    return ['?', 'B'].includes(reaction.emoji.name) && user.id === message.author.id;
                };

                message.awaitReactions(filter, { max: 1 })
                    .then(collected => {
                        if (reaction.emoji.name === '?') {
                            message.channel.send('Ok, so you want to buy a server. Let me recommend you to visit <#699374469977735208>.');
                        }
                        else {
                            message.channel.send('Ok, so you need more informations first. Let me recommend you to visit <#699374469977735208>.');
                        }    
                    })
            });

在显示代码之前，您直接调用的任何方法都不会返回

reaction。从回调函数中删除参数。然后，要访问应用的反应，您需要从Message#awaitReactions()返回的Collection中读取它。例如...

.then(collected => {
  const reaction = collected.first();
  // now you can check the reaction with the code you were using
})
