ProducesResponseType(typeof(void), ...) causes ApiExplorer to indicate the return type is ProblemDetails #7874
Description
Describe the bug
ApiExplorer/ProducesResponseType exposes incorrect value when the return type is void. It seems to override any attempt to indicate that the response produces no results/body with ProblemDetails.
To Reproduce
Steps to reproduce the behavior:
- Using this version of ASP.NET Core 2.2
- Apply the following attribute to an ApiController:
[ProducesResponseType(typeof(void), (int)HttpStatusCode.Unauthorized) - ApiExplorer indicates the return type is ProblemDetails.
Expected behavior
ApiExplorer should say the return type is void.
