Status code not respected for ApiException (AutoWrapper 5.0)

[nwoolls]

Hi there. I am trying out AutoWrapper 5.0 in an attempt to work around the problem described in issue #133.

With AutoWrapper 5.0, I am running into the following problem: when passing in a status code (e.g. 400) to the ApiException constructor, the resulting JSON object indicates the status code is 500.

You can reproduce this with the following steps.

From the command line:

dotnet --version
6.0.101
mkdir autowrapper-apiexception-issue
cd autowrapper-apiexception-issue/
dotnet new webapi
dotnet add package AutoWrapper.Core --version 5.0.0-rc-03

Edit Program.cs and add:

public class InputModel
{
    [Required(AllowEmptyStrings = false)]
    public string? FirstName { get; set; }
}

[HttpPost]
public IActionResult Post(InputModel inputModel)
{
    if (inputModel.FirstName == "foo")
    {
        throw new ApiException("An error occurred - throwing ApiException", StatusCodes.Status400BadRequest);
    }

    if (inputModel.FirstName == "bar")
    {
        throw new ApiProblemDetailsException("An error occurred - throwing ApiProblemDetailsException", StatusCodes.Status400BadRequest);
    }
    
    return StatusCode(StatusCodes.Status201Created);
}

Run the project.

The following are examples where throwing exceptions may result in a status code of 500 or 400.

Example 1 - Status Code is 500

curl -X 'POST' \
  'https://localhost:7006/WeatherForecast' \
  -H 'accept: */*' \
  -H 'Content-Type: application/json' \
  -d '{
  "firstName": "foo"
}'

{
  "isError": true,
  "errors": {
    "message": "An error occurred - throwing ApiException",
    "type": "ApiException",
    "source": "autowrapper-apiexception-issue",
    "raw": "   at autowrapper_apiexception_issue.Controllers.WeatherForecastController.Post(InputModel inputModel) in ..."
  },
  "validationErrors": null,
  "type": "https://httpstatuses.com/500",
  "title": "Internal Server Error",
  "status": 500,
  "detail": "An error occurred - throwing ApiException",
  "instance": "/WeatherForecast"
}

Example 2 - status code is 400

curl -X 'POST' \
  'https://localhost:7006/WeatherForecast' \
  -H 'accept: */*' \
  -H 'Content-Type: application/json' \
  -d '{
  "firstName": "bar"
}'

{
  "isError": true,
  "errors": null,
  "validationErrors": null,
  "type": "https://httpstatuses.com/400",
  "title": "An error occurred - throwing ApiProblemDetailsException",
  "status": 400,
  "detail": null,
  "instance": "/WeatherForecast"
}

This may be by-design due to the new defaults in AutoWrapper 5.0, but some clarity on this would still be much appreciated.

this seems to be an issue with 4.5 as well. e.g.

throw new ApiException("No User Found", statusCode: StatusCodes.Status400BadRequest);

will return 500 response regardless same as OP
