Describe the bug The code generator crashes.

To Reproduce Steps to reproduce the behavior:

Run

using the following OpenAPI schema (in JSON form, mini.json):

{
    "openapi": "3.0.1",
    "info": {
        "version": "1.0",
        "title": "Title"
    },
    "components": {
        "schemas": {
            "Registry": {
                "type": "string",
                "enum": [
                    "A",
                    "B",
                    ""
