Correct way to spec response by status code

[Farenheith]

Hello!

I'm testing your solution and it worked really well, but I got some problems and hope you could give me some guidance.

I have issues with status code 400 and 500 responses. Every time the api fails, the mcp fails as well with the following message:

TypeError: o.content is not iterable

In the container logs, I found the following

2025/11/04 16:11:11 [ExecuteToolCall] Request executed. Status Code: 400
2025/11/04 16:11:11 Received response body for tool 'getProductsBySearch': {"statusCode":400,"timestamp":"2025-11-04T16:11:11.711Z","path":"/v1/product/search","message":"Bad Request Exception","explicitMessage":"","data":["page must be a number conforming to the specified constraints","limit must be a number conforming to the specified constraints"]}

So, a structured return was detected, but maybe I did something wrong in the openai json.

"/v1/product/search": {
      "get": {
        "operationId": "getProductsBySearch",
        "parameters": [
          {
            "name": "application",
            "in": "header",
            "description": "Identificador da aplicação",
            "required": true,
            "schema": {
              "type": "string"
            }
          },
          {
            "name": "token-user-id",
            "in": "header",
            "required": true,
            "schema": {
              "type": "string"
            }
          },
          {
            "name": "token-user",
            "in": "header",
            "required": true,
            "schema": {
              "type": "string"
            }
          }
        ],
        "responses": {
          "200": {
            "description": "Esta chamada é usada para consultar produtos por termo de busca",
            "content": {
              "application/json": {
                "schema": {
                  "$ref": "#/components/schemas/RequestProductResponseDto"
                }
              }
            }
          },
          "400": {
            "description": "Requisição inválida ou erro de negócio.",
            "content": {
              "application/json": {
                "schema": {
                  "$ref": "#/components/schemas/ErrorResponseDto"
                }
              }
            }
          },
          "500": {
            "description": "Erro interno do servidor.",
            "content": {
              "application/json": {
                "schema": {
                  "$ref": "#/components/schemas/ErrorResponseDto"
                }
              }
            }
          }
        },
        "security": [
          {
            "access-token": []
          }
        ],
        "summary": "Consultar produtos pelo termo de busca",
        "tags": [
          "Product"
        ]
      }
    },

Do you have any tips I could work on to adjust my open ai spec, or is it a bug that need to be fixed (I could try to contribute if that's the case)
