DropWizard UnitOfWorkAwareProxyFactory injection

I am following the below link to add UnitOfWork on non resource methods.

Create @UnitOfWork-aware proxies of existing objects

The problem is

    @Inject UnitOfWorkAwareProxyFactory proxyFactory

calls the following method during application startup in Module

    @Provides
    @Singleton
    UnitOfWorkAwareProxyFactory provideUnitOfWorkAwareProxyFactory(HibernateBundle<AlexandriaConfiguration> hibernateBundle) {
        return new UnitOfWorkAwareProxyFactory(hibernateBundle);}

UnitOfWorkAwareProxyFactory calls hibernateBundle.getSessionFactory which is null at that time, which throws an exception.

Need a way to remove UnitOfWork from resource. I am using guice for dependency injection.
