Socket closed while trying to openDoc() about enigma.js HOT 5 CLOSED

I think that my issue is also network related, so I'm closing this issue until I can dig deeper on what is going on.
Thank you for your help!

If you connect through the Qlik Sense Proxy there is a maximum of 5 concurrent sessions. Best would be to connect directly to the engine using certificates. It would also be recommended to open the apps without data to open each app faster (if not already loaded into the engine memory).

Thank you for your feedback!
When I use the session cookie, I sometimes manage to edit more than 70 apps, so I figured that it was not the problem...
I will look into connecting directly to the engine, and that qNoData parameter.

Not sure how the virtual proxy is configured but looking at the console.log from your example it seems that the cookies have to do with AWS load balancer? If you set the JWT as authentication Bearer you don't need to worry about cookies.

Also if you want to connect through the proxy you could use something like bluebirds concurrency

const enigma = require('enigma.js');
const WebSocket = require('ws');
const Promise = require('bluebird');
const schema = require('enigma.js/schemas/12.20.0.json');

const config = {
  schema,
  url: 'ws://localhost:9076/app/',
  createSocket: (url) => new WebSocket(url),
}

const session = enigma.create(config);

(async () => {
  const global = await session.open();
  const apps = await global.getDocList();
  session.close();

  let infos = await Promise.map(apps, async appElm => {
    return await getDocInfo(appElm.qDocName);
  }, {concurrency: 4}); // Using 4 concurrent sessions to be safe 

  console.log("INFOS:", infos);

})().catch(err => {
  console.error(err);
});

const getDocInfo = async (appName) => {
  let localconfig = { ...config };
  localconfig.url += `${encodeURIComponent(appName)}`

  const localSession = await enigma.create(localconfig)
  const localGlobal = await localSession.open();
  const app = await localGlobal.openDoc(appName);
  const appInfo = await app.getAppProperties();
  localSession.close();

  return appInfo;
}
