Generation Details

Current output:

{
  "namespace": "model",
  "type": "record",
  "doc": "Describes the result of uploading an image resource",
  "name": "ApiResponse",
  "fields": [
    {
      "name": "code",
      "type": ["null", "int"],
      "doc": "",
      "default": null
    },
    {
      "name": "type",
      "type": ["null", "string"],
      "doc": "",
      "default": null
    },
    {
      "name": "message",
      "type": ["null", "string"],
      "doc": "",
      "default": null
    },
    {
      "name": "statuses",
      "type": ["null", {
        "type": "array",
        "items": "ApiResponseStatuses"
      }],
      "doc": "",
      "default": null
    }
  ]
}

Expected output (partially):

{
    {
      "name": "statuses",
      "type": ["null", {
        "type": "array",
        // BELOW LINE
        "items": "model.ApiResponseStatuses"
      }],
      "doc": "",
      "default": null
    }
}

Suggest a fix

The fix should be as simple as changing the mustache template for modules/openapi-generator/src/main/resources/avro-schema/typeArray.mustache
