I have issue my senior guess it because we failed force closed websocket.
We have application to show graph or qlik level by level and we have bookmark feature to save and view it again
the issue come if the qlik graph not last level, the issue only show on IE and Chrome.
At beginning i think this is because qlik.helper not loaded but some code related to qlik still working so i try to logout the qlik after the graph generated but windows pop-up show up
picture from console debug after all process completed and logout after 2-3 second error show up
