      requestBody:

        content:
          application/json:
            schema:

    Error:
      type: object
      properties:
        code:
          type: integer
        message:
          type: string
      required:
      - message
    Pn:
      type: integer
      format: int64
    dataInfo:
      type: string
    dataInfoStatus:
      type: string
      enum: [infoable, non_infoable,ignorable]

I am sending a single dataInfo in request and getting single dataInfoStatus in response, but I will like to send and array of dataInfo and get an array of dataInfo status.

I tried following:

schema:
  type:array
  items:
    $ref: "#/components/schemas/dataInfo"

but I get

Parser error bad indentation of a mapping entry

for items. I am following this.

How can I achieve sending dataInfo in request as an array of dataInfo and getting in response an array of dataInfoStatus?

Answer 1

You have to add one more space between type: and array, then the error message is gone:

schema:
    type: array
    items:
        $ref: "#/components/schemas/dataInfo"

And you can add the info.version for the version of the openapi file.
