Discord.js 我的机器人在 Heroku 上托管时找不到任何父频道或子频道

Question

Ok so i'm using Discord.js v12.4, and basically one command includes a 'category.children.forEach(...)', and it works fine locally. But when it's online, category.children returns an empty collection, and no channel has a parent, always null.

I did a 'guild.channels.cache.forEach(channel => console.log(channel.parent));' to check, and always null, null, null... Same with children...

Why would Heroku got trouble with children and parent channels ?

The original part of script ( works locally ) :

    let channels = [];
    let v_channels = [];
    modelCategory.children.forEach((channel) => {
        if(channel.type === "voice") v_channels[channel.position] = channel;
        else channels[channel.position] = channel;
    });
    channels = channels.concat(v_channels);
    console.log(channels);

But when the bot is hosted online :

>> []
