Hi ,

I have a C# DateTime Field as below

```
    [Date(Format = "yyyy-MM-ddThh:mm:ss",IgnoreMalformed =true)]
    public DateTime BirthdateTime { get; set; }

```

I'm getting below error , even after setting IgnoreMalformed =true, Is there anything I'm missing ?

Invalid format: "2017-12-05T17:04:01.4501539+05:30" is malformed at ".4501539+05:30"

Hi,

Is the index already created?  
Can you share the index mapping? GET index\_name/\_mapping
