Context

Given a request to a path similar to this:

http://localhost:8080/api/v1/config/SE/111

The path in spec looks like:

/config/{countryCode}/{uniqueId}:
  get:
    summary: Some summary
    description: Some desc
    operationId: the-op
    parameters:
      - $ref: '#/components/parameters/countryCode'
      - $ref: '#/components/parameters/uniqueId'

And a component section as:

components:
  parameters:
    countryCode:
      in: path
      name: countryCode
      schema:
        type: string
        pattern: '[A-Z]{2}'
      required: true
      description: The ISO 3166-1 2-alpha country code.
    uniqueId:
      in: path
      name: uniqueId
      schema:
        type: string
      required: true
      description: The id

The mentioned URL breaks with the following exception:
