Description

I want to generate an API client for R from this OpenAPI description, but the generation fails with the following error:

$ openapi-generator-cli generate

Generation Details

See above for the command used, the generator config file and openapi file.

Steps to reproduce
  1. Install the openapi-generator-cli (see the README of this repo)
  2. Create the folder api-client-r
  3. Add the following files to this folder
  4. From inside the folder api-client-r, generate the API client for R with openapi-generator-cli generate

The OA Generator (v6.6.0) for R works when fed with the Pet Store API description.

I can reproduce the error reported by doing the following modification to the Pet Store API description, where the commented code is replaced by $ref: '#/components/schemas/Customer':

...
  /pet/findByStatus:
    get:
      tags:
        - pet
      summary: Finds Pets by status
      description: Multiple status values can be provided with comma separated strings
      operationId: findPetsByStatus
      parameters:
        - name: status
          in: query
          description: Status values that need to be considered for filter
          required: false
          explode: true
          schema:
            $ref: '#/components/schemas/Customer'
            # type: string
            # enum:

Follow on the above example, turning the Customer component into type: string no longer throws an error:

    Customer:
      # properties:
      #   id:
      #     type: integer
      #     format: int64
      #     example: 100000

Code generation failed

The error is triggerd by the type associated to Customer. Setting it to type: object triggers the error; setting it to type: string or type: integer does not generate any error.

The OA Spec 3.0 says:

Query parameters can be primitive values, arrays and objects.

The Pet Store example does not include an example of query parameter that has type: object.

@wing328 I'm wondering whether what I'm experiencing is a bug or an unsupported feature even after looking at the page Documentation for the r Generator. There is a config option "errorObjectType" that may be related but its description is unclear.

fixed via #15953

please give it a try with the latest master (URL to snapshot version is in the readme)

@wing328 My setup consists in the config file openapitools.json and openapi-generator-cli generate.

{
  "$schema": "../../../node_modules/@openapitools/openapi-generator-cli/config.schema.json",
  "spaces": 2,
  "generator-cli": {
    "version": "6.6.0",
    "generators": {
      "api-client-r": {
        "generatorName": "r",
        "inputSpec": "#{cwd}/../api-description/build/openapi.yaml",
        "output": "#{cwd}/src/lib/",
        "additionalProperties": {
          "disallowAdditionalPropertiesIfNotPresent": false,
          "library": "httr"
        }
      }
    }
  }
}

What I tried to use the snapshot version:

  • In the config file, set the version to 7.0.0-SNAPSHOT or 7.0.0-20230630.114249-154 (taken from here). Based on the logs generated by OA Generator, my understanding is that these are not valid values because they don't exist on Mave (here).
  • I tried this command from the README, but the version specified in the config file (6.6.0) is still used: OPENAPI_GENERATOR_VERSION=7.0.0-SNAPSHOT openapi-generator-cli generate

What is the recommended way to try the snapshot version in this context?
