Scheduler AddTask false positive request success

Daemon returns ok response to AddTask request with non iso 8601 datetime format, but does not create a scheduler task file. It seems that the scheduler code detects error in the request, but returns successful response.

AddTask request:

{
    "mType": "mngScheduler_AddTask",
    "data": {
        "req": {
            "clientId": "SchedulerMessaging",
            "taskId": 1601384573748,
            "task": [
                {
                    "message": {
                        "mType": "iqrfRaw",
                        "data": {
                            "msgId": "testRaw",
                            "timeout": 1000,
                            "req": {
                                "rData": "00.00.06.03.FF.FF"
                            },
                            "returnVerbose": true
                        }
                    },
                    "messaging": "WebsocketMessaging"
                }
            ],
            "timeSpec": {
                "cronTime": [
                    "",
                    "",
                    "",
                    "",
                    "",
                    "",
                    ""
                ],
                "periodic": false,
                "period": 0,
                "exactTime": true,
                "startTime": "10:00:00"
            },
            "persist": true
        },
        "returnVerbose": true,
        "msgId": "87dbcbfe-6be2-483e-80df-1935a42d0af0"
    }
}

AddTask response:

{
    "mType": "mngScheduler_AddTask",
    "data": {
        "msgId": "87dbcbfe-6be2-483e-80df-1935a42d0af0",
        "rsp": {
            "clientId": "SchedulerMessaging",
            "taskId": 1573589862
        },
        "insId": "iqrfgd2-default",
        "statusStr": "ok",
        "status": 0
    }
}

However, task file is not created in filesystem.
