Copy and Paste this code in your index.cshtml.cs file

public class IndexModel : PageModel
{
private readonly ILogger _logger;
public JsonFileProductService _productService;
public IEnumerable Products { get; private set; }

    public IndexModel(ILogger<IndexModel> logger, JsonFileProductService productService)
    {
        _logger = logger;
        _productService = productService;
    }

    public void OnGet()
    {
        Products = _productService.GetProducts();
    }
}

After debugging i found that we did not give our field from class JsonFileProductService a value in the constructor.
