Policy evaluation not working in sails.js with passport - passport.js

Question

I've created a small API module, to have authenticated access for certain controllers using JWT.
Using local authentication to get the token, and JWT for subsequent end points
However the policies are not getting evaluated, it looks like middleware is not getting executed and sails is not evaluating the policy isSubscriber.js in the api/policies folder.
Here are the relevant code snippets:
/*
* Passport login strategy.
*/
const { JsonWebTokenError } = require('jsonwebtoken');
var passport = require('passport'),
LocalStrategy = require('passport-local').Strategy,
JwtStrategy = require ('passport-jwt').Strategy,
ExtractJwt = require ('passport-jwt').ExtractJwt,
md5 = require('md5');
passport.serializeUser (function(user, done){
done (null, user.id);
});
passport.deserializeUser(function (id, done){
Subscriber.findOne ({id: id}, function (err, user){
done(err, user);
})
});
var opts = {
jwtFromRequest: ExtractJwt.fromAuthHeaderAsBearerToken(),
secrtOrKey : 'xxxxx',
issuer: 'xxxxxx',
audience: 'xxxxx'
};
passport.use (new JwtStrategy(opts, function (jwt_payload, done){
sails.log ("Authenticating with JWT strategy");
Subscriber.findOne ({id: jwt_payload.id}, function (err, subscriber){
if (err){
return done (err, false);
}
if (user) {
return done(null, user);
} else {
return done(null, false);
}
});
}));
passport.use (new LocalStrategy({
usernameField: 'phone',
passwordField: 'password'
},
function (phone, password, done) {
sails.log ("Locating subscriber: " + phone + " Password: " + password);
Subscriber.findOne ({phone: phone}, function (err, subscriber){
if (err) { return done (err);}
sails.log ("Subscriber : " , subscriber);
if (!subscriber) {
sails.log ('User with phone ' + phone + ' not found!');
return done (null, false, {message : 'Subscriber not found.'});
}
sails.log ("Checking password: ");
if (md5(password) != subscriber.password_hash) {
sails.log ('Password mismatch for user ' + phone);
return done (null, false, {message: 'Invalid password'});
}
sails.log ("Successfully logged in");
return done(null, subscriber, {
message: 'Logged in succesfully.'
});
})
}
));
Middleware section in http.js
middleware: {
passportInit: require('passport').initialize(),
passportSession: require('passport').session(),
order: [
'cookieParser',
'session',
'passportInit',
'passportSession',
'bodyParser',
'compress',
'poweredBy',
'router',
'www',
'favicon',
]
policies:
module.exports.policies = {
'*': ['isSubscriber'],
'AuthController': {
'login': true // Always allow access to the user login action
}
};
isSubscriber.js:
module.exports = function (req, res, next){
sails.log ("Authenticating using jwt");
passport.authenticate ('jwt', function (error, user, info){
if (error) return res.serverError (error);
if (!user) {
return res.status(403).send ("Failed to authenticate");
}
req.user = user;
sails.log ("User authenticated, user record: " , req.user);
next();
})(req, res);
};
