De-synchronization fails

[darrudi]

Hi there,
I tried to make a de-synchronized version of execute but to no avail.
I checked out several popular node.js libraries including:

• node-sync
• deasync
• and finally sync
  All of them throw the following exception:

[TypeError: Object #<Object> has no method '_getAConnection']

Reproducing the error:

var Sync = require('sync');
var cql = require('node-cassandra-cql');

var client = new cql.Client({hosts: ['cassandra1.nikoo.ir', 'cassandra2.nikoo.ir'], keyspace: 'nikoomail'});

// Run in a fiber
Sync(function(){

    var result = undefined;

    try {
        result = client.execute.sync(null, 'SELECT * FROM nikoomail.user where username=?', ['darrudi@nikoo.ir']);
    }
    catch (e) {

        console.error('CQL query execution failed!');
        console.log(e);
        process.exit(-1);
    }

    console.log(result);
})

Thanks,
Ehsan
