sails-mongo auth error in sails 0.10

Using "sails-mongo": "^0.10.0-rc2", "sails": "~0.10.0-rc4" I'm getting the following error on sails lift.

This is on a local mongodb that is reachable in the mongo console.

my connection is configured by

  mongo: {
    adapter   : 'sails-mongo',
    host      : 'localhost',
    port      : 27017,
    user      : '',
    password  : '',
    database  : 'mle'
  },

Solution

in my case i am using url for connect mongodb like below

adapter: 'sails-mongo',
url: 'mongodb://<USERNAME>:<PASSWORD>@<HOST>/<DATABASE>'
