FromQuery Is not working for nested types

I have the following request object :

    public record SampleRequest
    {
        public int PageSize { get; set; }
        public int PageNumber { get; set; }
        public List<FilterModel> Filters { get; set; }
    }

    public record FilterModel
    {
        public string PropertyName { get; set; }
        public string PropertyValue { get; set; }
    }

And I'm trying to populate it from query for a HttpGet as following :

 [HttpGet]
 public IActionResult Get([FromQuery] SampleRequest request)
 {
       return Ok("");
 }

for testing I'm using SwaggerUI, but the binding it's not working for the Filter at all, it is always null. Any ideas?

In this case swagger can not help you to test. Use postman like:

localhost:5001?PageSize=10&PageNumber=1&Filters[0].PropertyName=test&Filters[0].PropertyValue=somevalue&Filters[1].PropertyName=test&Filters[1].PropertyValue=somevalue
