I need to make a interval refresh on my data table. But, the method doReload not works. On Engine API Explorer i receive invalid Status for doReload call in Doc.

And, in Javascript i receive the comming Object:

{
jsonrpc: '2.0',
id: 0,
error: {
code: -32602,
parameter: 'Invalid handle',
message: 'Invalid Params'
}
}

I able to call DOC and receive:

{
jsonrpc: '2.0',
method: 'OnConnected',
params: { qSessionState: 'SESSION_ATTACHED' }
}

{
jsonrpc: '2.0',
id: 2,
result: {
qReturn: {
qType: 'Doc',
qHandle: 1,
qGenericId: 'C:\\Users\\LDXNT25\\Documents\\Qlik\\Sense\\Apps\\DBTesting.qvf'
}
}

My Javascript code is:

const WebSocket = require('ws') module.exports = app => { function Repeating() { var ws = new WebSocket("ws://localhost:4848/app/C%3A%5CUsers%5CLDXNT25%5CDocuments%5CQlik%5CSense%5CApps%5CDBTesting.qvf") var openingDoc = { "jsonrpc": "2.0", "id": 2, "method": "OpenDoc", "handle": -1, "params": [ "C:\\Users\\LDXNT25\\Documents\\Qlik\\Sense\\Apps\\DBTesting.qvf" ] } var doReloading = { "handle": 1, "method": "DoReload", "params": { "qMode": 0, "qPartial": false, "qDebug": false } } ws.onopen = function(e) { console.log("Sending to server"); ws.send(JSON.stringify(openingDoc)) ws.send(JSON.stringify(doReloading)) } ws.onmessage = function(event) { console.log(JSON.parse(event.data)) } } setInterval(() => { Repeating() }, 25000); }

The question: What the erro? Im on Limited Account (30days)

In your "onopen" event handler it seems you are sending two messages on the websocket in quick succession: one to open the app and one to reload it. You probably have to wait for the open to finish before you can call the reload method.

ws.onopen = function(e) { console.log("Sending to server"); ws.send(JSON.stringify(openingDoc)) setTimeout(()=>{ ws.send(JSON.stringify(doReloading)) },1000) }

With this I think you can solve the error.
