Not too sure how to migrate off ExceptionProblemDetails

G’day 👋🏻

I’m migrating to v5 and noticed this warning about ExceptionProblemDetails becoming obsolete.

(note: ignore the code in the image, i just wanted to quickly take a screenie 😊 )

Old:

options.Map<ValidationException>(validationException => 
    new ExceptionProblemDetails(validationException, StatusCodes.Status400BadRequest));

New:

options.Map<ValidationException>(validationException => 
                    new ValidationProblemDetails(validationException.Errors.ToDictionary(key => key.PropertyName, value => new string[] { value.ErrorMessage }))
                    {
                        Status = (int)HttpStatusCode.BadRequest
                    });

I just feel that the updated way I’m doing/trying is … cumbersome?

Would love some thoughts…

I’m not sure a class like that would add a lot of value. The bulk of the code for validation errors would still be in the mapping from a validation exception into the dictionary, which you’d still need to write.

Yeah, the problem with DictionaryKeyPolicy is that it applies to all dictionaries, which could introduce problems with round-tripping. There is an issue for handling JsonExtensionData specifically, but that hasn’t moved anywhere; https://github.com/dotnet/runtime/issues/31167.
