Node-redis: exists method always returns true

[rahul]

var REDIS = require('redis')
var DB = REDIS.createClient()
console.log(DB.exists('some_key_not_already_in_db')) //prints true

Is there some other way of checking for existence?

[skenqbx]

try DB.exists('some_key_not_already_in_db', console.log)

Missed out on the callback.

Thank you!
