[0.12.0] NullPointerException

[mouhcine MOULOU]

Hello

I'm currently try to migrate to reactivemongo & play-reactivemongo to 0.12

I'm getting NullPointerException  when inserting new document: 

[info] f.k.c.d.OrderRepository - insert new document into order: Order(Some(BSONObjectID("58b5802d7f0000ce00147b6b")),587e322d671792645cd232c8,58b4220e0c000067007d7ab1,57b59a533b2ac552f6a50fc3,Map(57b59a527babdd3502ab099c -> 1),2017-03-31T02:00:00.000+02:00,16.5,16.5,pending,2017-02-28T14:50:37.747+01:00,false,Some(7.5),None)
