Can't call devise methods as soon as I upgraded to Mongoid 5

Below is the call trace...

Everything was working perfectly fine with Mongoid 4.2 and as soon as upgraded Mongoid to 5.0.0 I found this one!

Could you please help me out with this one? Not a clue how to debug this. Thank you in advance.

Mongoid 5 seems to have somewhat different mongoid.yml

I had the following mongoid.yml

development:
  clients:
    default:
      database: db-name
      hosts:
        - localhost:27017
      options:
        read: :primary_preferred

When I changed the value to read: from :primary_preferred to {mode: :primary_preferred} as follows, it did the trick!

development:
  clients:
    default:
      database: db-name
      hosts:
        - localhost:27017
      options:
        read:
          mode: :primary_preferred
