Source code this was produced from:
```c#
using JetBrains.Annotations;
using Microsoft.AspNetCore.Mvc.Filters;

namespace JsonApiDotNetCore.Middleware;

///
/// Converts action result without parameters into action result with null parameter.
///
/// return NotFound(null)
/// ]]>
///
/// This ensures our formatter is invoked, where we'll build a JSON:API compliant response. For details, see:
/// https://github.com/dotnet/aspnetcore/issues/16969
///
[PublicAPI]
public interface IAsyncConvertEmptyActionResultFilter : IAsyncAlwaysRunResultFilter;
```
