The current behavior

The parameters field contained in the Path Item Object is ignored.

The expected behavior

Processed in the same as the parameters included in the Operation Object.

Before

paths:
  /get/books/{id}:
    parameters:
    - name: id
      in: path
      required: true
      description: Book ID
      schema:
        type: string
        format: uuid
    get:
      operationId: getBookById
      responses:
        200:
          $ref: "#/components/responses/Books"

After

Since parameters is an Operation Object, it seems that it belongs to Paths differently.

paths:
  /get/books/{id}:
    get:
      operationId: getBookById
      parameters: // <----- here
        - name: id
          in: path
          required: true
          description: Book ID
          schema:
            type: string
            format: uuid
      responses:
        200:
          $ref: "#/components/responses/Books"

A list of parameters that are applicable for this operation. If a parameter is already defined at the Path Item, the new definition will override it but can never remove it. The list MUST NOT include duplicated parameters. A unique parameter is defined by a combination of a name and location. The list can use the Reference Object to link to parameters that are defined at the OpenAPI Object's components/parameters.

#47 (comment) is not wrong, but the implementation just doesn't seem to be faithful.

fixed: v0.9.4 higher version

Thanks !
