PassportJS Passport-local-mongoose - multiple local strategies not working

[prajwalsadaphal]

I'm developing a nodejs application and a I need two local strategies. The registration of both goes well, the problem is when I try to login with the enterprise user.

Heres is my code:

`let User = require('./models/userModel')
passport.use(User.createStrategy());
passport.serializeUser(User.serializeUser());
passport.deserializeUser(User.deserializeUser());

let Enterprise = require('./models/enterpriseModel')
let EnterpriseStrategy = require('passport-local').Strategy
passport.use('enterprise-local', new EnterpriseStrategy(Enterprise.authenticate()))
passport.serializeUser(Enterprise.serializeUser());
passport.deserializeUser(Enterprise.deserializeUser());

// Refactored code. But returns an error. ReferenceERROR: isUser is not defined
// passport.serializeUser(function(user, done) {
// if (isUser(user)) {
// done(null, User.serializeUser())
// } else if (isEnterprise(user)) {
// done(null, Enterprise.serializeUser())
// }
// });`

Some people told me that the problem is that I'm overriding the serialization. Then I used this commented code. But also return an error. isUser is not defined.

Could you achieve this with a user type variable/flag instead of multiple local strategies? I'm not sure if multiple local strategies are supported or not, just spitballing.
