DO_WHILE task results in "iteration" is not defined error

[anseltim]

I am trying to get a simple DO_WHILE task to work in a workflow. I am always getting this error:

Task *** failed with status: FAILED and reason: 'Unable to evaluate condition if ($.LoopTask[iteration] < $.value ) { true; } else { false; }, exception ReferenceError: "iteration" is not defined in at line number 1'

I have tried Conductor v3.15.0 and v3.10.0 with the same results. Any idea what I am doing wrong?

My example workflow definition:

{
    "name": "TEST_DO_WHILE",
    "description": "Testing Do While",
    "version": 1,
    "tasks": [
      {
        "name": "Loop Task",
        "taskReferenceName": "LoopTask",
        "type": "DO_WHILE",
        "inputParameters": {
          "value": 10
        },
        "optional": false,
        "asyncComplete": false,
        "loopCondition": "if ($.LoopTask['iteration'] < $.value ) { true; } else { false; }",
        "loopOver": [
          {
              "name": "test task",
              "taskReferenceName": "test_task",
              "inputParameters": {

                  }
              },
              "type": "HTTP"
          }
        ]
      }
    ],

i think you need have an previous step to generate the 'iteration', to read a JSON, file, etc.
