TypeError: Cannot read property 'password' of null

[anton6]

I was getting the following error when both the username and password are wrong:

Debug: internal, implementation, error 
web_1            |     TypeError: Cannot read property 'password' of null
web_1            |     at Query.<anonymous> (/usr/src/app/src/routes/account/handlers.js:176

At closer inspection it seems that loginUser handler is missing return keywords when reply(Boom.unauthorized('Authentication failed')); is called.
