allowableValues are not populated correctly when generating routes in REST DSL from an OpenAPI definition

From Karavan's VS Code extension, I've generated routes in REST DSL from the following OpenAPI definition: us-core-server.openapi.json. As far as I can tell, the allowableValues key is never populated correctly. For example:

Expected (as generated from JBang with Camel 4.4.0)

  - id: "createCareTeam"
    path: "/CareTeam"
    consumes: "application/fhir+json,application/fhir+xml"
    produces: "application/fhir+json,application/fhir+xml"
    param:
    - collectionFormat: "multi"
      dataType: "string"
      description: "Requests the server to return a designated subset of the resource"
      name: "_summary"
      required: false
      type: "query"
      allowableValues:
      - "true"
      - "text"
      - "data"
      - "count"
      - "false"
    - collectionFormat: "multi"
      dataType: "string"
      description: "Specify alternative response formats by their MIME-types (when\
        \ a client is unable acccess accept: header)"
      name: "_format"
      required: false
      type: "query"
    - collectionFormat: "multi"
      dataType: "boolean"
      description: "Ask for a pretty printed response for human convenience"
      name: "_pretty"
      required: false
      type: "query"
    - collectionFormat: "csv"
      dataType: "array"
      description: "Requests the server to return a collection of elements from\
        \ the resource"
      name: "_elements"
      required: false
      type: "query"
    - description: "The new state of the resource"
      name: "body"
      required: true
      type: "body"
    to: "direct:createCareTeam"

Actual (as generated from Karavan v4.4.0)

          collectionFormat: multi
          dataType: string
          allowableValues:

            - '0': t
              '1': e
              '2': x
              '3': t
            - '0': d
              '1': a
              '2': t
              '3': a
