Changing response type for automatic ModelState Validation

[HadiSDev]

Hi,

Is it possible to change the response body type of ASP.NET Core when ModelState automatically validates to false (If some fields are filled out incorrectly). Currently, my API responds with the standard body as:

{
    "errors": {
        "Password": [
            "The Password must be at least 6 characters long.",
            "The password has to have at least 1 upper-case letter and 1 number"
        ]
    },
    "type": "https://tools.ietf.org/html/rfc7231#section-6.5.1",
    "title": "One or more validation errors occurred.",
    "status": 400,
    "traceId": "|2dc1fb89-40f64e0f32438d5b."
}

Is it possible for me to change what should be included in the response body object? Like my own made class in C#?

Solved with this code:

            services.Configure<ApiBehaviorOptions>(apiBehaviorOptions => 
                    apiBehaviorOptions.InvalidModelStateResponseFactory = actionContext =>
                    {
                        var messages = actionContext.ModelState.Values.SelectMany(x => x.Errors.Select(m => m.ErrorMessage)).ToList();
                        return new BadRequestObjectResult(new ResponseBase<object>(){StatusCode = 400, Errors = messages, Data = null});
                    }
                );
