Discord vs bot 13 无法分配角色给出错误无法读取未定义的属性（读取 'guild'）

Question

我正在使用 discord js v13.6。我在我的代码中编写了在使用斜杠命令后为用户分配了许多角色，这些角色存储在名为 rolenumber 的数组中。问题是我每次都收到这个错误

 await client.users.fetch(memberId).then((user,interaction) => {
            user.send("Give me a few moments while I verify your details");
            (async function(user){

            
            let RoleArray = rolenumber.split(","); 
            //let guild = client.guilds.cache.get(guildNumber);
            //let member = await client.users.fetch(msg);   
            
            for(let num of RoleArray) {
                //console.log("Roles Inside a for loop",num);
                let role = interaction.guild.roles.cache.get(num);
                let data = await user.roles.add(role).catch(console.error);
                //user.roles.add(num).catch(console.error);            
            }   
            
           
            let welcomeMessage = 'Welcome <@'+ user.id +'>, you are now officially part of channel.';
            const channelMessage = await client.channels.cache.get(channelNumber);
            channelMessage.send(welcomeMessage);
        })();

这里的 guildNumber 是一个公会编号，出于安全原因，它在问题中是隐藏的。我收到此错误消息：

let role = interaction.guild.roles.cache.get(num);
                                       ^

TypeError: Cannot read properties of undefined (reading 'guild')

Answer 1

互动未定义您确定，交互传递到这里？

可以用但不完美

let role = interaction?.guild?.roles?.cache?.get(num);

Answer 2

Promise.prototype.then 的实现回调只需要 1 个参数。

await client.users.fetch(memberId).then((user) => {
            user.send("Give me a few moments while I verify your details")
            // ...
})

假设上面已经定义了interaction，它应该可以工作
