no find() method defined in adapter

[traskat]

I'm getting this error by a simple example:

error:

Error (E_UNKNOWN) :: Encountered an unexpected error
: No find() method defined in adapter!

by this code example:

var Waterline = require('waterline');
var sqliteWaterline = require('waterline-sqlite3');
var config = require('../config/config');
var serverMod = require('../model/servers');


// init waterline
var waterline = new Waterline();

serverMod.connections = 'sqlite';

var server = Waterline.Collection.extend(serverMod);

waterline.loadCollection(server);

waterline.initialize(config, function(err, models) {

    models.collections.data.find(function(err, servers) {
        console.log(err, servers);
    });
})

I had a look into the adapter and there is a find method also ig i am checkign with typeof like this

typeof(models.collections.data.find)

it return function.

any hints why this happens?

i am using node version v6.4.0. and waterline 0.12.2

thanks
