The code used to work, but somehow I forgot what I did with it and didn’t code for 2 months or so… The function should be – when you write !createcategory it should create a category with voice and text channels in it. The category should be named by your user name. There is no error in the console, please help, thanks!

Answer

I’m not sure what’s causing your issue, but try setting the parent of the text and voice channels when you create the channel:

// GuildChannelManager#create returns the channel you created
message.guild.channels.create(message.author.username, {
    type: 'category',
    permissionOverwrites: [
        {id: message.guild.id, deny: ['VIEW_CHANNEL']},
        {id: message.author.id, allow: ['VIEW_CHANNEL']},
    ]
}).then(parent => {
    // Create the text channel
    message.guild.channels.create('Text channel', {
        type: 'text',
        // under the parent category
        parent, // shorthand for parent: parent
        permissionOverwrites: [
            {id: message.guild.id, deny: ['VIEW_CHANNEL']},
            {id: message.author.id, allow: ['VIEW_CHANNEL']},
        ]
    }).catch(console.error)
    // Same with the voice channel
    message.guild.channels.create('Voice channel', {
        type: 'voice',
        parent,
        permissionOverwrites: [
            {id: message.guild.id, deny: ['VIEW_CHANNEL']},
            {id: message.author.id, allow: ['VIEW_CHANNEL']},
        ]
    }).catch(console.error)
})

You could also use ES2017’s async/await:

// Must be an async function      vvvvv
command(client, 'createcategory', async (message) => {
   // ...
   const parent = await message.guild.channels.create(/* ... */)
    try {
        // Run the promises concurrently, like in your code
        await Promise.all([
            message.guild.channels.create('Text channel', {/* ... */})
            message.guild.channels.create('Voice channel', {/* ... */)
        ])
    } catch (error) {
        console.error(error)
    }
    // ...
})
