Connecting to MongoDB in scala

I was trying to connect my play-scala application to mongo db through ReactiveMongo dependencies/ libraries that I found in play framework documentation.

I have added in my conf file like this

play.modules.enabled += "play.modules.reactivemongo.ReactiveMongoModule"
mongodb.uri = "mongodb://ege:ege123@localhost:27017/smug-studio"

but after running my application, when I am trying to access the database through postman api it throws me an exception like 

{
    "Code": 0,
    "ERROR": "MongoError['Connection is missing metadata (like protocol version, etc.) The connection pool is probably being initialized.']"
}

in the logs I could find like this

[warn] r.c.a.MongoDBSystem - [Supervisor-1/Connection-2] Error while processing getNonce response #1000
[error] r.c.a.MongoDBSystem - [Supervisor-1/Connection-2] Authentication failure
reactivemongo.core.commands.FailedAuthentication: BSONCommandError['Error while processing getNonce response #1000']

What should I required to do to fix the issue?

If you can connect to mongo on the shell, then the issue might be that you have not set the authMode or authMechanism correctly on the url:

mongodb://ege:ege123@localhost:27017/smug-studio?authMechanism=SCRAM-SHA-1

or

mongodb://ege:ege123@localhost:27017/smug-studio?authMode=SCRAM-SHA-1
