question

The cloud script call does not respond back with any useful information, but it is executed correctly (only the answer does not).

Result

Simplified code:

handlers.CheckDailyBonus = function() {
  try {
    console.log("CheckDailyBonus enter");
    ...code
    return CreateDialyBonusResponce(false, streak, streak);
  } catch (ex) {
    console.log(ex);
  }

  function CreateDialyBonusResponce(success, balanceChange, currentStreak, error) {
    var responceForClient = {
      "Success": !error && success,
      "BalanceChange": balanceChange,
      "Streak": currentStreak,
    };
    if (error)
      responceForClient["Error"] = error;

    console.log("CreateDialyBonusResponce responceForClient=" + responceForClient);
    return JSON.stringify(responceForClient);
  }
};
