Setup

class CustomError extends Error {
  constructor(message) {
    super(message);
    this.name = "CustomError";
  }
}

class CustomError2 {
  constructor(message, err) {
    this.name = "CustomError";
    this.message = message;
    this.err = err;
  }
  get stack() {
  	return this.err.stack;
  }
}
Reflect.setPrototypeOf(CustomError2.prototype, Error.prototype);

class CustomError3 extends Error {
  constructor(message) {
    super(message);
    this.name = "CustomError";
    this.stack2 = this.stack;
  }
}
