Fail to Retrieve Content

I try to get content items with this code to try get the content:

[assembly: RegisterWebPageRoute(
    ContentSection.CONTENT_TYPE_NAME,
    typeof(BlogController),
    ActionName = nameof(BlogController.GetContentList))]

namespace HEJAZ.Frontend.Web.Features.Hejaz.Blog;

[ApiController]
[Route("api/[controller]")]
public class BlogController : WebPageControllerBase
{
    private readonly ILogger<BlogController> _logger;
    private readonly IMediator _mediator;
    private readonly IContentQueryExecutor _contentQueryExecutor;

    public BlogController(
        IMediator mediator,
        IContentQueryExecutor contentQueryExecutor,
        ILogger<BlogController> logger)
        : base(mediator)
    {
        _logger = logger;
        _mediator = mediator;
        _contentQueryExecutor = contentQueryExecutor;
    }

    [HttpGet]
    public async Task<IActionResult> GetContentList([FromQuery] GetContentListQuery query)
    {
        ContentItemQueryBuilder builder =
            new ContentItemQueryBuilder()
                .ForContentType(
                    ContentSection.CONTENT_TYPE_NAME,
                    subqueryParameters =>
                {
                    subqueryParameters.TopN(5);
                }).InLanguage("en");

        IEnumerable<ContentSection> blogs =
            await _contentQueryExecutor.GetMappedResult<ContentSection>(builder);

        return Ok();
    }
}

when debugging the code hit the line 39. i got error on my postman:
