vendor extension inside "items"

[nickfun]

Hey guardrail is a super great project and I love it but I'm here to report a bug:

Generating clients for akka-http. Using the maven plugin 0.59.0.

In my spec file I choose a x-jvm-type nested inside some request paramters on a Post. The generated client ends up taking String instead of the type I specified.

Example snippet:

  /v1/Services/{ServerlessServiceSid}/Builds:
    post:
      tags:
        - "Builds"
      x-jvm-package: "Serverless"
      summary: "Create a build of the service"
      operationId: "createBuild"
      parameters:
        - $ref: "#/components/parameters/ServerlessServiceSid"
      requestBody:
        required: true
        content:
          application/x-www-form-urlencoded:
            schema:
              required:
                - AssetVersions
                - FunctionVersions
                - Dependencies
              properties:
                AssetVersions:
                  type: array
                  items:
                    x-jvm-type: ServerlessFileVersionSid         # !
                    example: ZN00000000000000000000000000000000  # !
                    type: string                                 # !
                FunctionVersions:
                  type: array
                  items:
                    x-jvm-type: ServerlessFileVersionSid         # !
                    example: ZN00000000000000000000000000000000  # !
                    type: string                                 # !
                Dependencies:
                  type: string
      responses:
        201:
          description: "Created"
          content:
            application/json:
              schema:
                $ref: "#/components/schemas/ServerlessBuildResource"
        400:
          $ref: '#/components/responses/BadRequest'
        404:
          $ref: '#/components/responses/NotFound'
        500:
          $ref: '#/components/responses/InternalServerError'

The generated client has this:

def createBuild(serverlessServiceSid: ServerlessServiceSid, assetVersions: Iterable[String], functionVersions: Iterable[String], dependencies: String, headers: List[HttpHeader] = Nil): EitherT[Future, ServiceClientError, CreateBuildResponse]

I expected the two Iterable[String] to be Vector[ServerlessFileVersionSid]

Have attempted a workaround of moving the #! lines above to a $ref but generated client didn't change.

Just some further info so I don't forget, because I got confused about this:

• This does work for array properties in an object specified in components/schemas (or definitions for Swagger v2).
• This does not work for array parameters specified on a request.
• This does not work for array properties in an object specified in-line in a requestBody.

Ultimately we want to unify these things so we don't need this code in three places; they are separate because the Swagger v2 used different model representations, but the OAPI v3 parser does actually model these things the same way.
