channel.permissionOverwrites returns too many arguments.

[VirtuesL]

Please describe the problem you are having in as much detail as possible:

The methods guild#createChannel and channel#clone do not work, throwing out a (node:12252) UnhandledPromiseRejectionWarning: RangeError: Invalid permission string or number.

This seems to be because the <channel>.permissionOverwrites returns 6 arguments instead of 4. To be exact it returns allowed, and denied. According to discord API documentation it only accepts 4 arguments.

Include a reproducible code sample here, if possible:

// Place your code here
message.channel.clone()
//or
message.guild.createChannel(<name>, "text",  message.channel.permissionOverwrites)

Further details:

• discord.js version: 11.4.2
• Node.js version: v10.10.0
• Operating system: Windows 10
• Priority this issue should have – please be realistic and elaborate if possible:

• [ ] I found this issue while running code on a user account
• [x] I have also tested the issue on latest master, commit hash: 3418b5a

Bumping this because I'm getting the error again My code:

module.exports = {
    name: 'purge',
    description: 'Removes a number of messages in a channel',
    args: true,
    guildOnly: true,
    async execute(message, args) {
        // console.log(message.client)
        const authorguildmember = message.guild.members.find(member => member.id === message.author.id);
        if (!authorguildmember.hasPermission('MANAGE_MESSAGES')) return message.channel.send('You are not allowed to delete messages');
        const clientguildmember = message.guild.members.find(member => member.id === message.client.user.id);
        if (!clientguildmember.hasPermission('MANAGE_MESSAGES')) return message.channel.send('I don\'t have the manage messages permission!');
        if (!(parseInt(args[0]) || (args[0]) === 'all')) return message.channel.send('Please enter a valid number between 1 and 99');
        if (args[0] === 'all') {
// ERROR OCCURS ON LINE BELOW
            const newchannel = await message.channel.clone(undefined, true, true, 'purged all');
            message.channel.send(`Please move to ${newchannel}, this channel will be deleted`);
            setTimeout(message.channel.delete, 3000, ['Purged']);
        } else {
            let amountToDelete = parseInt(args[0]) + 1;
            while (amountToDelete) {
                if (amountToDelete >= 100) {
                    message.channel.bulkDelete(100, true);
                    amountToDelete -= 100;
                } else {
                    message.channel.bulkDelete(amountToDelete, true);
                    amountToDelete = 0;
                }
            }
        }
    },
};

So, as the original post mentions, it's very likely the TextChannel.clone() function. Error:

RangeError: Invalid permission string or number.

Since you are on 11.4.2 try updating to 11.5.1, this sounds like a bug which was fixed there. See the relevant changelog entry:

• Permissions.resolve not accepting a Permissions instance (5d889be6db65acc44f3a443b78d3165f9d6c0ed2)
