v13 中的成员角色？

Question

I had a userinfo command in v12, but i made a fully new bot in v13 and i don't know if i can use the same code again. I tried using this:

let mem = message.mentions.members.first() || message.member

const filteredRoles = mem.roles.cache.filter(role => role.id != message.guild.id)
const listedRoles = filteredRoles.sort((a, b) => b.position - a.position).map(role => role.toString())

//...code...

.addField('Roles:', listedRoles)

Error:

C:\Users\-----\-----\-----\node_modules\discord.js\src\util\Util.js:413
    if (typeof data !== 'string') throw new error(errorMessage);
                                        ^

RangeError [EMBED_FIELD_VALUE]: MessageEmbed field values must be non-empty strings.

Answer 1

The MessageEmbed.addField() method accepts a string as its second parameter (the field's value). Your listedRoles is an array, you can use Array.join() to convert it into a string.

.addField("Roles: ", listedRoles.join(","))

Example working code:

client.on("messageCreate", async (message) => {

    if (message.author.id == client.user.id) return;

    if (message.content.startsWith("!roles")) {
        const member = message.mentions.members.first() || message.member;
    
        const filteredRoles = member.roles.cache.filter(role => role.id != message.guild.id);
        const listedRoles = filteredRoles.sort((a, b) => b.position - a.position).map(role => role.toString());
    
        const embed = new Discord.MessageEmbed()
            .setTitle(member.user.username)
            .addField("Roles", listedRoles.join(","));
    
        message.channel.send({embeds: [embed]});
    }

});
