I have implemented passport local strategy and passport google strategy to implement login functionality,my google strategy is working fine but when am login with local strategy its calling the serializable and deserializable method of passport's google strategy.
I have made separate instances for both (i.e both for local and google strategy) , still the serializableUser and deserializableUer method of only google strategy is getting called for both the strategies as the result req.user remains undefined in case of local strategy since the user is not setting in the session
i have visited a lot of stackoverflow questions but i didn't get any solution, finally i am wondering that is it even possible to use passport local strategy and passport google stategy to implement login functionality in the same project?
My Question is similar to this ( the serialize and deserialze methods are not getting called separately )
app.js
here googleS and localS are instances of two different strategies i.e, local and google sttrategies.

The problem here is that when i am doing login by local strategy its still calling the serialize and deserialize methods of google strategy and as a result unable to set the user of local strategy into session so its returning undefined on req.user. why its happening , am i wrong anywhere? Please suggest ,I am in the need of an immediate help, i am stuck with this problem from the last three days. Any help is greatly appreciated and i will be very thankful for the person.
