Web API Getting Http 500 error : Issue Solved See Below
- by Joe Grasso
Here is my MVC Controller and everything is fine:
private UnitOfWork UOW;
public InventoryController()
{
UOW = new UnitOfWork();
}
// GET: /Inventory/
public ActionResult Index()
{
var products = UOW.ProductRepository.GetAll().ToList();
return View(products);
}
Same method call in API Controller gives me an Http 500 Error:
private UnitOfWork _unitOfWork;
public TestController()
{
_unitOfWork = new UnitOfWork();
}
public IEnumerable<Product> Get()
{
var products = _unitOfWork.ProductRepository.GetAll().ToList();
return products;
}
Debugging shows that indeed there is data being returned in both controllers' UOW calls. I then added a customer configuration in Global:
public static void CustomizeConfig(HttpConfiguration config)
{
config.Formatters.Remove(config.Formatters.XmlFormatter);
var json = config.Formatters.JsonFormatter;
json.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
}
I am still receiving an Http 500 in API Controller ONLY and at a loss as to why. Any ideas?
UPDATE:
It appears using lazy loading caused the problem. When I set the associated properties to NON-VIRTUAL the Test API provided the necessary JSON string. However, whereas before I had the Vendor class included, I only have VendorId. I really wanted to included the associated classes. Any ideas? I know there are alot of smart people out there. Anyone?
