NullReferenceException on GetEnumDescription

[yefka]

Hi, I got an issue with

The issue occurs while opening the swagger webpage, on this line in DefinitionsBuilder.cs :
DescriptionAttribute[] array = (DescriptionAttribute[])value.GetType().GetField(value.ToString()).GetCustomAttributes(typeof(DescriptionAttribute), inherit: false);

the value is System.Reflection.TypeAttributes.Public, and System.Reflection.TypeAttributes.Public.GetType().GetField(System.Reflection.TypeAttributes.Public.ToString()) returns null, so GetCustomAttributes raises this exception.
