How to return a static response in kong api-gateway

Question

I am using kong API-gateway in its DB-Less mode

as a result, I have a kong.yaml file as below:

_format_version: "2.1"
_transform: true

services:
  - name: service1
    url: http://service1:port/sample-path
    routes:
      - name: service1
        methods:
          - GET
        paths:
          - /service1/sample-path
        strip_path: true

As you see, the api-gateway dispatches requests from /service1/sample-path endpoint of api-gatway to http://service1:port/sample-path

I am looking for a way to add a new service such that when a request is sent to /oas endpoint of api-gateway, it loads a yaml or json file and return that as the response.

In action, I am looking for a way to return a static response instead of dispatching the request?

Any idea how to do this?

pseudo code

_format_version: "2.1"
_transform: true

services:
  - name: service1
    url: http://service1:port/sample-path
    routes:
      - name: service1
        methods:
          - GET
        paths:
          - /service1/sample-path
        strip_path: true
  - name: oas
    url: STATIC YAML OR JSON FILE
    routes:
      - name: oas
        methods:
          - GET
        paths:
          - /oas
        strip_path: true
