If you take a look at the ExpressJS source for res.status you will see that the function expects a Number, not a String:

/**
 * Set status `code`.
 *
 * @param {Number} code
 * @return {ServerResponse}
 * @public
 */

res.status = function status(code) {
  this.statusCode = code;
  return this;
};
