In order to init the Server class, 2 arguments are passed (config.server and options) in the second argument (options) there are 3 values (cert, Chanel and app instance). however, Chanel and the app instance require directly in the Server class file. 1. during Server class initialization port info does not pass into the class and the server has no chance to start correctly 2. Chanel requires incorrectly, it exports like `module.exports = Chanel` but requires like `const { Chanel } = require(../)` please lose curly braces here 3. application requires incorrectly, it exports like `module.exports = application` but requires like `const { application } = require(../)` please lose curly braces here
