Nested arrays as paramaters to cloud function are serialized incorrectly

[mykelp]

Issue Description

When sending up parameters for a cloud function, one of my parameters is an array with nested arrays. After version 2.2.11, the nested arrays are being converted into objects.

Steps to reproduce

Send up a request to a cloud function with a parameter as an array with nested arrays.

Expected Results

{ 
  "param": [
    [“equalTo", "seller", { "className": "Organization", "objectId": "rWYBWWgE1b"}],
    ["equalTo", "status", 1],
    ["notEqualTo", "buyer", { "className": "Organization", "objectId": "rWYBWWgE1b" }],
    ["include", "buyer"],
    ["ascending", "buyer.canonicalName"],
    ["skip", 0],
    ["limit", 100]
    ]
}

Actual Outcome

{ 
  "param": [
   { '0': 'equalTo’, ’1’: 'seller','2': { className: 'Organization', objectId: 'rWYBWWgE1b' } },
   { '0': 'equalTo', '1': 'status', '2': 1 },
   { '0': 'notEqualTo', '1': 'buyer', '2': { className: 'Organization', objectId: 'rWYBWWgE1b' } },
   { '0': 'include', '1': 'buyer' },
   { '0': 'ascending', '1': 'buyer.canonicalName' },
   { '0': 'skip', '1': 0 },
   { '0': 'limit', '1': 100 }
   ]
}

To help us debug this, can you include the exact request and response in Parse Server, as well as your cloud code? (you can see this in the logs using VERBOSE=1 environment variable)

Hi @drew-gross

I work with @mykelp. I don't get a response as it causes our server to crash. Here is the request:

  verbose: POST /parse/functions/customer { host: 'localhost:3004',
  connection: 'keep-alive',
  'content-length': '546',
  origin: 'http://localhost:3004',
  'user-agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.103 Safari/537.36',
  'content-type': 'text/plain',
  accept: '*/*',

  'accept-language': 'en-US,en;q=0.8',

  "query": [
    [
      "equalTo",
      "seller",
      {
        "className": "Organization",
        "objectId": "qhlLQxW3iY"
      }
    ],
    [
      "equalTo",
      "status",
      1
    ],
    [
      "notEqualTo",
      "buyer",
      {
        "className": "Organization",
        "objectId": "qhlLQxW3iY"
      }
    ],
    [
      "include",
      "buyer"
    ],
    [
      "ascending",
      "buyer.canonicalName"
    ],
    [
      "skip",
      0
    ],
    [
      "limit",
      100
    ]
  ],
  "sellerId": "qhlLQxW3iY"
}

Here is what the query parameter from the request logs on the server

[ { '0': 'equalTo',
    '1': 'seller',
    '2': { className: 'Organization', objectId: 'qhlLQxW3iY' } },
  { '0': 'equalTo', '1': 'status', '2': 1 },
  { '0': 'notEqualTo',
    '1': 'buyer',
    '2': { className: 'Organization', objectId: 'qhlLQxW3iY' } },
  { '0': 'include', '1': 'buyer' },
  { '0': 'ascending', '1': 'buyer.canonicalName' },
  { '0': 'skip', '1': 0 },
  { '0': 'limit', '1': 100 } ]

The goal of the code is to reconstruct a query object on the server

bug is still actual for parse server 2.2.16

cloud function:
Parse.Cloud.define('test', function(request, response) { console.log(request.params); response.success(request.params); });

request:
curl "http://$host/parse/functions/test" -H 'Content-Type: application/json;charset=UTF-8' -H "X-Parse-Application-Id: $appId" --data-binary '{"shouldBeArray": [["a", "b"]]}'
response:
{"result":{"shouldBeArray":[{"0":"a","1":"b"}]}}
