AutoLangConfig for Label Doesn't Seem to Work in this Case

[markpbaggett]

When using the library, a common pattern is to set an auto language across the manifest so that you don't need to set the language each time. For instance:

config.configs['helpers.auto_fields.AutoLang'].auto_lang = "en"
base_url = "https://iiif.io/api/cookbook/recipe/0001-mvm-image"
manifest = Manifest(id=f"{base_url}/manifest.json", label="Single Image Example")

With this, the lang of the label would be 'en'. For some reason, that pattern doesn't work in this case:

config.configs['helpers.auto_fields.AutoLang'].auto_lang = "en"
natural_light = ResourceItem(
    id="https://iiif.io/api/image/3.0/example/reference/421e65be2ce95439b3ad6ef1f2ab87a9-dee-natural/full/max/0/default.jpg",
    type="Image",
    format="image/jpeg",
    width=2000,
    height=1271,
    label="Natural Light"
)

Instead, this results in:

Traceback (most recent call last):

    natural_light = ResourceItem(

    ...<4 lines>...
        label="Natural Light"
    )

label -> __root__

Expected behaviour:

I expected to be able to set the language for the ResourceItem with config.configs['helpers.auto_fields.AutoLang'].auto_lang = "en".

Observed behaviour:

An error was raised:

Traceback (most recent call last):

Potential bug location(s):

Not sure yet. I looked in auto_fields.py, but I haven't spotted the problem yet.

Any other comments:

As ResourceItem inherites from Base not Class it needs to be added directly here:
