Get Request/Model Body in ASP.NET Core Exception Filter without Replay

I have a several models that share an interface, it looks like

public interface IRequest {
    public string RequestId { get; set; }
}

An example of a model that implements this look like

public class CatRequest : IRequest {
    public string RequestId { get; set; }
    public string Name { get; set; }

I have a CatController that looks like

public class CatController: ControllerBase {
    [HttpPost]
    public IActionResult AddCat([FromBody] cat) {
        // call database and add cat to db
    }
}

Knowing fully well that several things can go wrong in the database operation, I have a global exception filter that works and it looks like

public void OnException(ExceptionContext context) {
    // create a proper error response message
    var error = new ErrorResponse() {
        ResponseCode = 400,
        RequestId = 2, // HERE IS THE SPOT, I WANT TO READ RequestId from the RequestBody or Model without re-reading the request

        // The solution below works, but only when it is a custom exception where I had previously manually added the Data entry
        // RequestId = context.Exception.Data["RequestId"]?.ToString()
    };
    context.Result = new JsonResult(error);
}

Can I get a better implementation?

Thanks.
