List of Recursive Models

[RGBKnights]

I have a Field class that list columns that is also a Field.

public class Field 
{
    public Guid Id { get; set; } 
    public string Name { get; set; }
    public string Type { get; set; }
    public List<Field> Columns { get; set; }
}

Everything I know about the OpenAPI spec tells me this should be possible but the whole application crashes trying to render the swagger UI with a System.StackOverflowException.

I am experiencing the same issue. Some more details:

My minimally reproducible model:

    public class Category
    {
        public IList<Category> Children { get; set; }
    }

Error occurs when requesting the swagger.json file

swagger.json was requested.
Stack overflow.

Workaround (-ish):
Changing
[OpenApiResponseWithBody(HttpStatusCode.OK, "application/json", typeof(Category), Example = typeof(CategoryExample))]
to
[OpenApiResponseWithBody(HttpStatusCode.OK, "application/json", typeof(object), Example = typeof(CategoryExample))]

Though it now obviously does not expose the actual model.

The issue may be related to #54

Any movement on this? I'm seeing the same issue with a recursive data type even when the property is set to null in my OpenApiExample type.

  public class CategoryGetManyExample : OpenApiExample<CategoryModel>
    {
        public override IOpenApiExample<CategoryModel> Build(NamingStrategy namingStrategy = null)
        {
            Examples.Add(OpenApiExampleResolver.Resolve("Exmaple Category", new CategoryModel { Name = "Category", Subcategories = null }, namingStrategy));

            return this;
        }
    }

I think this issue related to #167

[justinyoo]

@level120 Not really. Recursive error is a separate issue.

I have the same issue. I looked at the PR (#138 ) solving #54 and the fix that was made does not check for IEnumerable of Type.

Could that be a possible solution @justinyoo?

[choipureum]

Can I look for a solution?

Considering the existence of recursive visitors, it does not seem to work in the form of a data structure including recursive.

[justinyoo]

@choipureum Sure. I'll assign it to you.

[tsolbjor]

I have the same issue and a possible solution in #233

[decocsa]

Should this be fixed in Feature/#156? I still have the same issue.
