Issue with blueprints group

I am try to use blueprints group: but I am getting:

Traceback (most recent call last):
File “/Users/smaj/PycharmProjects/x/”, line 33, in
TypeError: ‘dict’ object is not callable

Python 3.7 and Sanic 19.9.0.

should be app.blueprint(group) in line 33

app.blueprints returns a dict of all registered blueprints in the sanic app
