I don't understand why this happens and what can I do to resolve it. Please point me in the right direction.

Thank you.

The error is in your own code, as you can see from the stack trace (repositories.UserRepository.authenticate). The error seems unrelated to Morphia. We're going to need to see the code or at least have context on what else you've done.

The problem is that in you application.conf you have set mongoClientFactory where you haven't the class.

Comment the line and all should works fine.
