Answer 1

In your command.execute() call, you are passing in client as the fourth parameter. But in your command file, where you export the giveaway command, client is the third parameter.
module.exports = {
name : 'giveaway',
// Add cmd parameter here, so client is passed in correctly as the fourth parameter
execute : async(message, args, cmd, client) => { ... }
}
