When web api model not valid

 [HttpPost]
    public BaseResponseModel ResetUser([FromBody]ResetUserModel request)
    {        
        return !ModelState.IsValid ? new BaseResponseModel() : _test.test(request);
    }

Hi everyone, If my ModelState isn't valid, my api return this model.

{
"Message": "The request is invalid.",
"ModelState": {
    "request.EMail": [
        "E-posta Hatalı"
    ]
}

}

But I want to return my BaseResponseModel. How I can do? Thanks
