validatePayloads not working

[markartur]

Validate Payloads is true in my inflector.yaml file.
I am generating a response payload that is missing a required field, but no error is being throw , neither in logs or on the API.

My inflector.yaml file:

swaggerUrl: swagger.yaml
validatePayloads: true
environment: production
controllerPackage: com.adp.datacloud.accessmanagement.api
modelPackage: com.adp.datacloud.accessmanagement.model
modelMappings:
User: com.adp.datacloud.accessmanagement.model.UserResource
Role: com.adp.datacloud.accessmanagement.model.RoleResource
Group: com.adp.datacloud.accessmanagement.model.GroupResource
entityProcessors:

• json

My API definition on swagger.yaml:

/groups:
get:
tags:
- groups
x-swagger-router-controller: GroupApi
operationId: getGroups
summary: Get groups list
parameters:
- in: header
name: clientoid
type: string
description: 'Unique key identifier for client'
required: true

  responses:
    200:
      description: Success response
      schema:
        items:
          $ref: '#/definitions/Group'

definitions:

Group:
required:
- groupoid
- name
properties:
groupoid:
type: string
name:
type: string
terminated:
type: string

The object that my code is generating:

[ { "name": "Standard Practitioners" }, { "name": "Custom Group 1" } ]

Missing the required groupoid field, but no error happens.
