Hi, using service stack 5.0.2

given this dto

[Route("/persons/events/subCategories", "PUT")]
public class SetEventPersonSubCategories
: IReturn
{
[ApiMember(IsRequired = true, ParameterType = "body", Name = "subcategories")]
public List Subcategories { get; set; }
//public SubCategoryWrite Subcategories { get; set; }
}

the generated schema is :

'/persons/events/subCategories':
put:
tags:
- persons
operationId: SetEventPersonSubCategoriespersonideventseventidsubCategories_Create
consumes:
- application/json
produces:
- application/json
*parameters:
- name: subcategories
in: body
type: array
items:
$ref: '#/definitions/SubCategoryWrite'
collectionFormat: multi
required: true
responses:
'200':
description: Success
schema:
$ref: '#/definitions/SetEventPersonSubCategoriesResponse'
deprecated: false
parameters:
- $ref: '#/parameters/Accept'

gives the following schema errors in https://editor.swagger.io/

**Schema error at paths['/persons/{personid}/events/{eventid}/subCategories'].put.parameters[0]

additionalProperty: type, items, collectionFormat, name, in, required

As you can see , there is something wrong with the array declaration ,

if I replace
public List Subcategories { get; set; }
with
public SubCategoryWrite Subcategories { get; set; }

it does not complain anymore

Can you please help ?

Don't use body, the entire Response DTO is the body of the Response not just the Subcategories property.
