Flask-Restless not accepting hybrid_property

Question

I have a hybrid property like this

@hybrid_property
def address(self):
    return ', '.join([
        self.address_street,
        self.address_city,
        self.address_state,
        self.address_zip
        ])

@address.setter
def address(self, address):
    g = geocoder.google(address)
    if g.street_number and g.street_name:
        self.address_street = g.street_number + ' ' + g.street_name
    if g.city:
        self.address_city = g.city
    if g.state:
        self.address_state = g.state
    if g.postal:
        self.address_zip = g.postal
    if g.latlng:
        self.address_lat = g.lat
        self.address_lng = g.lng

@address.expression
def address(cls):
    return cls.address_street + ', ' + cls.address_city + ', ' + cls.address_state + ', ' + cls.address_zip

Using a basic Flask-Restless API...

manager = APIManager(app, flask_sqlalchemy_db=db)
member_bp = manager.create_api(
    Member,
    collection_name='members',
    methods=['GET', 'POST', 'PATCH'],
    include_columns=[
        'id',
        'first_name',
        'last_name',
        'email',
        'created_at',
        'signup_code',
        ]
    )

But Flask-Restless gives me a 400 and says Model does not have field 'address'. I have another hybrid_property that I am setting as well, but it doesn't complain about that. I can't figure out what's wrong with this hybrid_property.

The weird thing is that I can expose the property in my API through the include_columns parameter.
