Parse Cloud Code not responding to error or success with promises

Question

My cloud code does not respond with error or success. It's just time, I don’t know what I'm doing wrong. It should save several values ​​in different tables and end up sending a push message to the user.

The pressed message and the user table are configured and sent, but street and register objects are not saved correctly. Also the answer is not called.

I worked in the past (or I was just lucky). Any thought on what I am doing wrong?

  var buyerId = request.params.buyerid;
  var sellerName = request.params.sellername;
  var streetId = request.params.streetid;
  var amount = request.params.amount;
  var pushMessageTemplate = request.params.pushMessage;

  var log = request ? request.log : console;
  var Streets = Parse.Object.extend('SHStreets');
  var streetQuery = new Parse.Query(Streets);
  streetQuery.equalTo("objectId", streetId);
  streetQuery.first({
    useMasterKey: true,
    success: function (street) {
      var streetName = street.get("name");

      var query = new Parse.Query(Parse.User);
      query.equalTo("objectId", buyerId);
      query.first({
        useMasterKey: true,
        success: function (user) {
          var promises = [];
          var now = new Date();

          var buyerName = user.get("username");
          // Set and save the change
          user.set("balance", user.get("balance") - amount);
          user.set("streets", user.get("streets") + 1);

          street.set("current_owner", user);
          street.set("owned_since", now);
          street.set("for_sale", false);
          street.set("price_bought", amount);

          var acl = new Parse.ACL();
          acl.setPublicReadAccess(true);
          acl.setWriteAccess(user, true);
          street.setACL(acl);

          //update ledger
          var Ledger = Parse.Object.extend("Ledger");
          var ledger = new Ledger();

          ledger.set("type", "buy");
          ledger.set("amount", amount);
          ledger.set('ledger_time', now);
          ledger.set("user", user);
          ledger.set("description", "x");

          promises.push(Parse.Object.saveAll([street, user, ledger], { useMasterKey: true }));

          // Find users with a given email
          var userQuery = new Parse.Query(Parse.User);
          userQuery.equalTo("objectId", user.id);

          var pushQuery = new Parse.Query(Parse.Installation);
          pushQuery.exists("user"); // filter out installations without users
          pushQuery.include('user'); // expand the user pointer
          pushQuery.matchesQuery("user", userQuery);

          // Send push notification to query
          promises.push(Parse.Push.send({
            where: pushQuery, // Set our installation query
            data: {
              alert: _.template(pushMessageTemplate)({
                sellername: sellerName,
                streetname: streetName,
                amount: amount
              })
            }
          }, {
              useMasterKey: true,
          }));

          return Parse.Promise.when(promises).then(function () {
            response.success("success");
          });
        },
        error: function (error) {
          log.error('buy-street error', error.message);
          response.error("Uh oh, buy request success failed." + error.message);
        }
      });
    },
    error: function (error) {
      log.error('buy-street error', error.message);
      response.error("Uh oh, buy request success failed." + error.message);
    }
  });

Answer 1

I have lost a functional error for returning promises.

 return Parse.Promise.when(promises).then(function () {
    // Set the job sucess status
    response.success('success');
 },function(error) {
    response.error(error);
 });

Answer 2

, :

streetQuery.first({
useMasterKey: true,
success: function (street) { // this function doesn't return anything
  // ...
  query.first({  // You probably want to return this promise
    useMasterKey: true,
    success: function (user) { // this is the function that you're returning to
      // ...
      return Parse.Promise.when(promises).then(function () {
        response.success("success");
      });
    },
  });
}

});

Javascript undefined , return.
