@MohamedElgarnaoui I have tried that solution but still doesn't work same problem — Kinuthia, Jul 06 '17 at 13:10
I was actually doing it the wrong way. It is not advisable to connect to MongoDB directly it is recommended to use an API. And that solved my problem. — Kinuthia, Jul 07 '17 at 08:40

I was actually doing it the wrong way. It is not advisable to connect to MongoDB directly it is recommended to use an Rest API. And that solved my problem.
