Error: collection name must be a String

Hi,

I'm getting this error "Error: collection name must be a String" when I try to call read method.

`routes.read({number: '1004'})
  .then(function(result){
    console.log('Result', result);
  }).catch(function(err){
    console.log('Error:',err);
  });`

Also, there's no live example on using mongodb.

Best Regards
