Generating a python client with openAPI reference files is not working.

[nateg-sr]

Describe the bug

This error response object has an empty key, which causes the openapi-generator to generate invalid code with a type hint for a missing class member, like the following:

class UpdateSettingsStorefrontSeo422ResponseErrors(BaseModel):
    """
    UpdateSettingsStorefrontSeo422ResponseErrors
    """ # noqa: E501
    : Optional[Annotated[str, Field(min_length=1, strict=True)]] = None
    __properties: ClassVar[List[str]] = [""]

To Reproduce

Run the following from the root of this repository to generate a python client

docker run \
  --rm \
  -v .:/local \
  docker.io/openapitools/openapi-generator-cli generate \
  --input-spec-root-directory /local/reference \
  -o /client \
  -g python \
  --package-name bc

Expected behavior

The key should have a name, or the parent field should be a string instead of an object.
