Flask-security: AttributeError: 'NoneType' object has no attribute 'send'

I get this error while trying to register an user:

AttributeError: 'NoneType' object has no attribute 'send'

I am using Python 2.7.3, Flask 0.9, Flask-Security 1.5.0 and Flask-Mail 0.7.3

From the interactive debugger:

[console ready]
>>> current_app
<LocalProxy unbound>
>>> current_app.extensions.get('mail')
Traceback (most recent call last):

I believe this is because you haven't created and configured the Flask-Mail extension. I need to make the documentation clearer that you need to do this yourself. Take a look at the test app to see what to do:

Solved thanks!
I configured Mail just trough the config keys I thought flask-security was initializing it for me.

The link is no longer available can someone please help me on how to fix this issue ?

Looks like you have to initialize the Mail object yourself:

mail = Mail()
app = Flask(__name__)
mail.init_app(app)

(from https://pythonhosted.org/Flask-Mail/)

This makes sense because Flask-Security lists all features that use Flask-Mail as optional
