I tried various online editors like jsonlint.com etc but nothing is validating my JSON data.

```
[
{
    "id": "1234",
    "dataSourceId": "1234",
    "location": "localhost",
    "schema": "null",
    "frequency": {
        "start": "12",
        "end": "10",
        "pattern": {
            "daily": "daily",
            "weekly": [
                'Sunday',
                'Monday',
                'Tuesday',
                'Wednesday',
                'Thursday',
                'Friday',
                'Saturday'
            ],
            "monthly": "17"
        }
    },
    "type": "db",
    "format": "sql",
    "lastUpdated": "2014-09-16",
    "userId": "123",
    "jsonblob": "null"
}
]

```

Why weekly object is showing error, however everything is correct in chrome console.
