Is there any way how I can disable DisallowNull generation

Hi. For specific reason I have an API that has method with parameter and returned value with the same type.

class HelloObject{
[Required]
  string SomeProp {get;set;}
}
----
HelloObject Index(HelloObject) {
}

In this DTO one property is marked with DataAnnotation [Required] for validation of incoming parameter. But output model can have null value there.

But. If I generate definition with NSwag i will get

        [Newtonsoft.Json.JsonProperty("SomeProp", Required = Newtonsoft.Json.Required.DisallowNull, NullValueHandling = Newtonsoft.Json.NullValueHandling.Ignore)]
        public string SomeProp { get; set; }

And will get an exception while invoking this method in generated Client.

Required property ‘SomeProp’ expects a non-null value. Path ‘[0].HelloObject’, line 1, position 354.

I’ve tried:

                    RequiredPropertiesMustBeDefined = false,
                    GenerateDataAnnotations = false,

same as both states of NullHandling So is there any way how to disable DisallowNull generation?

The best option is to transform the generated swagger spec before generating client code (ie with an own cmd line tool which uses the nswag.core lib).

In general I think flexibility in library and tool is important, so I suggest to add this option into NSwag
