How to save app details

[ChandrashekharB]

I am using Nodejs for the Qlik connection, I want to save the app created in the Qlik sense.

Used params as follows :

{

"jsonrpc": "2.0",

"id": 6,

"method": "DoSave",

"handle": 1,

"params": [

"example.qvf"

]

}

I am getting :

{
 jsonrpc: '2.0',
 id: 6,
 error: {
   code: -32602,
   parameter: 'Invalid handle',
   message: 'Invalid Params'
 }
}

 please help me to solve this...
