Trying to add data in unsupported state at Cipher.update

Question

Below code is working

var crypto = require(\'crypto\');
var cipher = crypto.createCipher(\'aes-128-cbc\',\'abcdefghijklmnop\')
var http = require(\'http\')

         


        

Answer 1

Turns out

var cipher = crypto.createCipher('aes-128-cbc','abcdefghijklmnop')

should not be reused. I put it into the server callback too and the problem is solved.
