Why is not bulkDelete working in discord.js?

Question

I tried to make a bulk delete command to my discord bot, but it doesn't work.

const args = message.content.slice(prefix.length).trim().split(/ +/g);

if(args[1] == 'bulkdelete') {
  const deleteCount = parseInt(args[2], 10);
  message.channel.bulkDelete(deleteCount || 100)
    .then(() => message.reply('Removing messages'))
    .catch(console.error);
}

When I try to use it, it returns an error. TypeError: Object.entries(...).filter(...).flatMap is not a function

What am I doing wrong?

Answer 1

I don't know what part of the code is specifically causing the error TypeError: Object.entries(...).filter(...).flatMap is not a function, but given that this error is occurring, I may know a fix.

Object.entries() returns an array, array.filter() returns an array, and arrays in node.js v11+ have the function property flatMap(). Since the error is telling you that the flatMap() property is not a function on an array, you're probably using an older version of nodeJS.

To fix this, you need to update to node 11 or a newer version.
