Cannot use nested objects in response

[matthew-kaye]

Is there an existing issue for this?

• I have searched the existing issues

Current behavior

I think this issue was closed without a real fix. When trying to generate a Swagger document, it will create required fields as a boolean rather than an array, for example if you defined a class like this:

class AddressResponseDTO {
  status: string;
  data: {
    line1: string;
    line2?: string;
    city: string;
    province?: string;
    postalCode: string;
    country: string;
  };
}

it generates the following:

{"type":"object","properties":{"status":{"type":"string"},"data":{"type":"object","properties":{"line1":{"type":"string","minLength":1,"required":true},"line2":{"type":"string","required":true},"city":{"type":"string","minLength":1,"required":true},"province":{"type":"string","required":true},"postalCode":{"type":"string","minLength":1,"required":true},"country":{"type":"string","minLength":1,"required":true}}}},"required":["status","data"]}

Minimum reproduction code

#2117

Steps to reproduce

1. Define a class with a nested object or array of objects as the response type
2. Generate a Swagger document
3. Observe required fields are boolean when required fields should be defined by a separate array

Expected behavior

The required field should only ever be an array, not a boolean
