Description

"type": "array",
              "items": {
                  "type": "object",
                  "properties": {
                      "first_name": {
                          "type": "string"
                      },
                      "profile_picture_url": {
                          "type": "string",
                          "nullable": True,
                      },
                  },
                  "required": [
                      "unique_id",
                      "first_name",
                      "last_name",
                      "profile_picture_url",
                  ],
              }

In this example OpenAPI spec, I get a generated type where profile_picture_url is of type string, not string | undefined or string | null.

Reproducible example or configuration

"type": "array",
              "items": {
                  "type": "object",
                  "properties": {
                      "first_name": {
                          "type": "string"
                      },
                      "profile_picture_url": {
                          "type": "string",
                          "nullable": True,
                      },
                  },
                  "required": [
                      "unique_id",
                      "first_name",
                      "last_name",
                      "profile_picture_url",
                  ],
              }
