Answer 1

It says that the guild property is undefined, this might be because someone's using the command in DM's and that's why you're not getting the guild. So what you can do is add an if statement to check if the user is using the command in a server
Here's an example:
module.exports = {
name: "ticket",
aliases: [],
permissions: [],
description: "open a ticket!",
async execute(message, args, cmd, client, discord) {
if (!message.guild) return message.channel.send("You can't use this command in DM's");
// Rest of the code
}
};
