unhappy to convert json lists

[muelli]

it seems to be unhappy to transform my nested structure containing a list:

➜ json-to-elm git:(master) ✗>python generate.py form.json 
Generating type alias, decoders and encoders from form.json
Traceback (most recent call last):
  File "generate.py", line 131, in <module>
    main()
  File "generate.py", line 127, in main
    print_everything(f.read(), name)
  File "generate.py", line 55, in print_everything
    aliases = create_type_alias(stuff, type_alias_name=alias_name)
  File "/home/muelli/vcs/json-to-elm/type_alias.py", line 49, in create_type_alias
    for name, value in stuff.items():
AttributeError: 'list' object has no attribute 'items'
➜ json-to-elm git:(master) ✗>

The structure looks like this:

[
    {
        "id": 1,
        "name": "form1",
        "form": {
            "tabs": [
                {
                    "id": 1,
                    "name": "some topic",
                    "fields": [
                        {
                            "key": "02",
                            "name": "q1",
                            "description": "foo?",
                            "is_required": true,
                            "default_value": null,
                            "state": "active"
                        }
                    ]
                }
            ]
        }
    }
]
