Stack Overflow when null is parsed

[yasassri]

Refer the following Swagger definition, If you try to process this it will result a stackoverflow error. This is dueto the null property parsed as an Enum.

   ],

      }
   }
}

I was able to fix this in the following manner. Please fix this issue.

While errors should be more graceful, null is not a valid value in Swagger definitions.
Have a look at swagger-api/swagger-js#507.
