Expression error when using a having('key').between(1, 10)

I using the library and working good. In this point I found this error. I resolved this error using the native aws-sdk and works well.

##Error

{
  "message": "Value provided in ExpressionAttributeValues unused in expressions: keys: {:create_at_2_v1, :create_at_1_v1}",

##Example

//...
    function (init, end) {
        const def = new Defer();
        const initDate = new Date(init);
        const endDate = new Date(end);

        console.log(+initDate, +endDate); // log for test
        
        dynamodb
          .table('table')
          .having('key1').null()
          .having('create_at').between(+initDate, +endDate)
          .scan(function(err, data) {
              if (err) return def.reject(err);
              def.resolve(data);
          });

        return def.promise;
    }

I see the problem, I’ll try to reproduce

[adrianpraja]

released version 0.1.60,

with minimum changes this fixed my local replication of your described issue.

I still can not recommend using

	var $users = DynamoDB.table('users')
	$users.insert(...)
	$users.update(...)
	...

there are no tests to confirm that is ready for this change.

I’m closing the issue for now, please re-open it if you still see the issue.

Thanks </adrian>
