Workflow:

1. run node index
2. see error

---

It happens only if you have multiple responses (see path/clusters.yaml and path/users.yaml) referencing same file in multiple paths.

eg.

clusters > 200, 400
users > 200, 400
# 400 must reference the same response

---

Having:

get:
  tags:
    - Users
  description: Returns a list of users
  operationId: getUsers
  responses:
    "200":
      $ref: "../responses/users.yaml"
    "400":
      $ref: "../responses/400.yaml"

This will fail:

get:
  tags:
    - Clusters
  description: Returns a list of clusters
  operationId: getClusters
  responses:
    "200":
      $ref: "../responses/clusters.yaml"
    "400":
      $ref: "../responses/400.yaml"

This will NOT fail:

get:
  tags:
    - Clusters
  description: Returns a list of clusters
  operationId: getClusters
  responses:
    "200":
      $ref: "../responses/clusters.yaml"

It will not fail, if you reference response only once:

clusters > 200, 400
users > 200

or

clusters > 200
users > 200, 400

npm run test to validate spec file
