SOLVED: DiscordJS v14: Expected undefined or null, Expected a bigint primitive, Expected a number pr-CodePudding

I am trying to make a ban command and this error keeps popping up:

ban.js:

const { SlashCommandBuilder, PermissionFlagsBits } = require('discord.js');

const botPerms = [
    PermissionFlagsBits.SendMessages,
    PermissionFlagsBits.ReadMessageHistory,
    PermissionFlagsBits.BanMembers,
];

module.exports = {
    data: new SlashCommandBuilder()
        // Command name. Example: /choices
        .setName('ban')
        // Command's description. Shows up in commands menu once / is typed.
        .setDescription('Bans specified user')
        .setDefaultMemberPermissions(botPerms)
        .addUserOption(option =>
            option
                .setName('user')
                .setDescription('User to ban.')
                .setRequired(true),
        )
        .addStringOption(option =>
            option
                .setName('reason')
                .setDescription('Why was the user banned?')
                .setRequired(true),
        ),

    async execute(interaction) {
        if (interaction.guild.members.me.permissions.has(botPerms)) {
            const user = interaction.options.getUser('user');
            const reason = interaction.options.getString('reason');

            if (user.bannable === true) {
                interaction.guild.members.ban(user);
                interaction.reply('Banned!');

                try {
                    user.send(`You have been banned from ${interaction.guild.name}!\nReason::${reason}`);
                }

                catch (error) {
                    interaction.followUp('Failed to DM banned user.');
                }
            }
        }
    },
};

deploy-commands.js:

const { REST, Routes } = require('discord.js');
const { clientId, token } = require('./config.json');
const fs = require('node:fs');

const commands = [];
// Grab all the command files from the commands directory you created earlier
const commandFiles = fs.readdirSync('./commands').filter(file => file.endsWith('.js'));

// Grab the SlashCommandBuilder#toJSON() output of each command's data for deployment
for (const file of commandFiles) {
    const command = require(`./commands/${file}`);
    commands.push(command.data.toJSON());
}

// Construct and prepare an instance of the REST module
const rest = new REST({ version: '10' }).setToken(token);

// and deploy your commands!
(async () => {
    try {
        console.log(`Started refreshing ${commands.length} application (/) commands.`);

        // The put method is used to fully refresh all commands in the guild with the current set
        const data = await rest.put(
            Routes.applicationCommands(clientId),
            { body: commands },
        );

        console.log(`Successfully reloaded ${data.length} application (/) commands.`);
    }
    catch (error) {
        // And of course, make sure you catch and log any errors!
        console.error(error);
    }
})();

What's wrong? I as well couldn't find anything about it on the internet. The logs don't really help, but I for sure know the error is caused by ban.js. No idea how though.

node deploy-commands.js and node init.js — both gave out same error. I am really clueless about it.

CodePudding user response：

Firstly, you are not handling your error. You'll get a nicely formatted error if you catch it... so catch it!

Moving on to the problem, .setDefaultMemberPermissions(botPerms) is the issue. Let's explain the logs: it says it expected undefined or null, a bigint, a number or a string. However, you gave [2048n, 65536n, 4n]. An array, of course, is none of these. This is why you get the error.

You cannot give a list of permissions here. You should do const botPerms = PermissionFlagsBits.SendMessages | PermissionFlagsBits.ReadMessageHistory | PermissionFlagsBits.BanMembers instead. The | is a bitwise OR which joins the permissions together, setting the default member permissions to all of these.

Here is the relevant documentation link: https://discordjs.dev/docs/packages/builders/main/SlashCommandBuilder:Class#setDefaultMemberPermissions
