Microsoft.AspNetCore.Mvc.Filters.ActionFilterAttribute isn't working properly with .Net Core 2.2

I am not sure if this is a correct repository to report the issue related to Microsoft.AspNetCore.Mvc, but can you please redirect to correct one if found this one as incorrect? Here is the issue:
I am using Microsoft.AspNetCore.Mvc.Filters.ActionFilterAttribute for my .Net Core 2.2 project. Below is the type of my controller:

public IActionResult Post([FromBody] IEnumerable<NewObject> input)
        {
            xyz.CreateObjects(input);
            return NoContent();
        }

With that I am using following API from ActionFilterAttribute in my class:

public override void OnActionExecuting(ActionExecutingContext actionContext)
{
............
}

Now though I am passing correct JSON structure from my test cases, the actionArguments is coming as an empty. This used to work in .Net Framework with System.Web.Http.Filters.ActionFilterAttribute

with below code:
public override void OnActionExecuting(HttpActionContext actionContext)

But now with .Net Core I am not able to use that.

It was mistake from my side where I didn't set SerializerSettings
