Answer 1

An error I noticed on your code, is that you are requesting permissions with the hasPermission() modal. In v13 (version I suppose you are using), this modal is deprecated.
Here is a solution that may work for you:
const { MessageEmbed, Permissions } = require('discord.js');
if (!message.member.permissions.has([Permissions.FLAGS.MANAGE_CHANNELS])) {
return message.channel.send('Wait, you cannot lock channels!')
}
What I am doing here is requesting the Permissions object from the Discord.js library, to use it with your chosen flag (FLAGS.MANAGE_CHANNELS), and then checking if it has the flag you expect with the has() modal.
This is only what I saw on the command's code, though. Your error log shows an error on index.js:4:16, so it may be a good idea to share your index.js file to see if there are other errors present on it.
