无法读取未定义的属性“成员”（discord.js）

Question

我正在尝试创建一个 DM 验证系统，如果成员将 DM 发送到机器人，他就会被接受。

....

const respectrumServer = client.guilds.cache.get('782347082362912768');

client.on('message', message => {   
    if (message.author.equals(client.user)) return;

    var authorid = message.author.id;

    if (message.toString().toLowerCase() === "lonely guy is the best") {
    
        if (message.channel.type == "dm") {

                if(respectrumServer.members.cache.has(authorid)){
                   //error is here ^
                    var verifiedrole = member.respectrumServer.roles.cache.find(role => role.id === '782348009362161714');
                    var notverifiedrole = member.respectrumServer.roles.cache.find(role => role.id === '797218539563122688');

                    member.roles.add(verifiedrole);
                    member.roles.remove(notverifiedrole);
                    authorid.send('You have been verified');

                }
                else{
                    authorid.send('You are not a member of Respectrum');
                }

        }
        else{
            message.channel.send('I know, right?');
        }
    }
    else{
        return;
    }
    
});

我改变了很多东西，比如 message.author 到 message.author.id 和 members.cache.find(authorid) 到 members.cache.has(authorid)

我不知道是什么问题。

这是因为您试图在机器人准备好之前获取respectrumServer 服务器。 当您收到一条新消息时，请改用以下代码来定义它：

client.on('message', async message => {  
    if (message.author.equals(client.user)) return;

    const respectrumServer = client.guilds.cache.get('782347082362912768');
    var authorid = message.author.id;

    if (message.toString().toLowerCase() === "lonely guy is the best") {
    
        if (message.channel.type == "dm") {
                const member = await respectrumServer.members.fetch(authorid).catch(() => {});
                if(member){
                   //error is here ^
                    var verifiedrole = member.respectrumServer.roles.cache.find(role => role.id === '782348009362161714');
                    var notverifiedrole = member.respectrumServer.roles.cache.find(role => role.id === '797218539563122688');

                    member.roles.add(verifiedrole);
                    member.roles.remove(notverifiedrole);
                    authorid.send('You have been verified');

                }
                else{
                    authorid.send('You are not a member of Respectrum');
                }

        }
        else{
            message.channel.send('I know, right?');
        }
    }
    else{
        return;
    }
    
});
