joinedAtTimeStamp is showing Nan discord.js-CodePudding

I was coding a userInfo command but when I use the command, the joinedAtTimeStamp is showing <t:NaN:R> in the embed. It's the only problem in this code.

My code:

const { MessageEmbed, ContextMenuInteraction } = require("discord.js");

module.exports = {
    name: "userInfo",
    aliases: ["user"],
    permissions: ["SEND_MESSAGES", "ATTACH_FILES"],
    description: "user",

    async execute(message, args, cmd, client, Discord, profileData) {
        const target = message.mentions.users.first();
        if(!args[0]) {
            const response2 = new MessageEmbed()
            .setColor("RANDOM")
            .setAuthor({name: message.author.tag, iconURL: message.author.displayAvatarURL({dynamic: true})})
            .setThumbnail(message.author.displayAvatarURL({dynamic: true}))
            .addFields(
                {name: "ID", value: message.author.id},
                {name: "Joined Server", value: `<t:${parseInt(message.author.joinedTimestamp / 1000)}:R>`, inline: true},
                {name: "Account Created", value: `<t:${parseInt(message.author.createdTimestamp / 1000)}:R>`, inline: true},
                
            );
            message.reply({embeds:[response2]});
        }
        const response = new MessageEmbed()
            .setColor("RANDOM")
            .setAuthor({name: target.tag, iconURL: target.displayAvatarURL({dynamic: true})})
            .setThumbnail(target.displayAvatarURL({dynamic: true}))
            .addFields(
                {name: "ID", value: target.id},
                {name: "Joined Server", value: `<t:${parseInt(target.joinedTimestamp / 1000)}:R>`, inline: true},
                {name: "Account Created", value: `<t:${parseInt(target.createdTimestamp / 1000)}:R>`, inline: true},
            );
            
        message.reply({embeds: [response], ephemeral: true})
    }
}

I am using discord.js v13 and node 16.

CodePudding user response：

message.author is a User and it doesn't have a joinedTimestamp property, only GuildMembers have. message.member represents the author of the message as a guild member, so you can use that as it will have a joinedTimestamp property.

The reason you see NaN instead of the correct value is because parseInt will return NaN if you try to parse undefined:

console.log('undefined:', parseInt(undefined / 1000, 10));
console.log('3459192421512:', parseInt(3459192421512 / 1000, 10));

The following code should work as expected

.addFields(
  { name: 'ID', value: message.author.id },
  {
    name: 'Joined Server',
    value: `<t:${parseInt(message.member.joinedTimestamp / 1000, 10)}:R>`,
    inline: true,
  },
  {
    name: 'Account Created',
    value: `<t:${parseInt(message.author.createdTimestamp / 1000, 10)}:R>`,
    inline: true,
  },
);

As for target, it's the same issue; message.mentions.users.first() is a User. You could create a new variable, e.g. targetMember and assign message.mentions.members.first(), so it will be a GuildMember:

const target = message.mentions.users.first();
const targetMember = message.mentions.members.first();

And then, just replace target:

.addFields(
  { name: 'ID', value: target.id },
  {
    name: 'Joined Server',
    value: `<t:${parseInt(targetMember.joinedTimestamp / 1000, 10)}:R>`,
    inline: true,
  },
  {
    name: 'Account Created',
    value: `<t:${parseInt(target.createdTimestamp / 1000, 10)}:R>`,
    inline: true,
  },
);

PS: It's a good idea to use the radix in parseInt. That's why I added 10 as the second parameter in parseInt.

CodePudding user response：

Could you verify the type of target.joinedTimestamp?

It could be that the double conversion you are doing here:

parseInt(target.joinedTimestamp / 1000)

destroyed your number.

(You are converting whatever target.createdTimestamp is to number, dividing it by 100 (making it a floating point number) and then discarding the floating point by converting back to int.)
