when trying to list the users in my instance (see following code)

syncano.connect(api_key=API_KEY)
users = User.please.list(instance_name=INSTANCE)
for user in users:
    # print(user)
    print(user.user_key)

I get the following error:

Traceback (most recent call last):

I tested my api key in http://docs.syncano.io/v0.1.1/docs/users-list and it worked. It looks like the python lib cant create a user model object from the response.

Code from the stacktrace

   def serialize(self, data, model=None):
        """Serializes passed data to related :class:`~syncano.models.base.Model` class."""
        model = model or self.model
        if data == '':
            return

        if isinstance(data, model):
            return data

        if not isinstance(data, dict):
            raise SyncanoValueError('Unsupported data type.')

        properties = deepcopy(self.properties)
        properties.update(data)
        return model(**properties) if self._serialize else data`
