Я сталкиваюсь с ошибкой «Ошибка типа: не удается прочитать свойство ‘client’ неопределенного» при написании моей команды в я думаю, что из этой строки я правильно ее написал? (я не совсем уверен, так как я новичок в программировании и получал помощь от друга) Кстати, я использую discord v12

 if(client.guilds.cache.get(order.guildID).client.me.hasPermission("CREATE_INSTANT_INVITE")) {
                                // Send message to cook.
                                

                                message.reply(`Order has been sent to ${client.guilds.cache.get(order.guildID).name}`);
                                
                                
                                // Get invite.
                                
                            }else {
                                // Bot delivers it's self.
                                client.channels.cache.get(order.channelID).send(`${client.users.cache.get(order.userID)}, Here is your taco that you ordered. Remember you can do `.tip [Amount]` to give us virtual tips, and `.feedback [Feedback]` to give us feedback on how we did. ${order.imageURL}`);

                                
                                
                                // Logs in console.
                                console.log(colors.green(`The bot did not have the Create Instant Invite Permissions for ${client.guilds.get(order.guildID).name}, so it delivered the taco itself.`));
                            }
 

если это не было проблемой, полный код для команды находится здесь:

Вам не требуется добавлять client при проверке разрешений клиента. Вы можете просто использовать следующее, чтобы проверить права доступа вашего клиента:

 if(client.guilds.cache.get(order.guildID).me.hasPermission("CREATE_INSTANT_INVITE")) {
   // code here
}
