App not opening - Qlik Sense

[Qlik_NZ]

Hi,

I have a client with a very old Qlik Sense instance (April 2020 Patch 4), and due to multiple circumstances updating the QLik instance is not a viable option at the moment.

With that said, there is an app which is an Extract app (SQL Server to QVD files) and it runs every hour. The issue is, when I clone that app and try to open it to check its code (as it is starting to go over 1h) Qlik just stays on the "Opening the app" message and nothing happens... even downloading the app without data and trying to open it after doesn't work.

Any idea how I can overcome this issue? Maybe the "never-ending" reload is causing this somehow?

Any and all help/ideas will be much appreciated.

Thank you.

Do you have the source code? a copy of the file? is the copy file not opening too? is it the same case with other files too?

Did you try to remove all objects from the file?(charts,.table etc)

You can do that thru QMC...

Maybe that will help.

Hi Qrishna,

I do not have the source code. And this also happens with a copy of the file as I mentioned, I downloaded the QVF, uploaded it, still won't open.

Re the other files, no issues that I can find, I can and have been cloning and opening other apps.

Hi Robert,

No I haven't tried that. I did export the app without data, and still no luck. But can you send me a link where the steps to do that are explained, so I can give it a try with one of the cloned apps?

Thank you.

Thongs to try.

Navigate straight to the script editor try to manipulate the url so you open the script editor view and not the app gui views.

Open without data. I don't remember when this feature was released, but it has been possible to open an app without any data by the right click menu in the HUB. (This will help you bypass any Section access issues that occurs)

Open the app in Qlik Sense Desktop. If you have access to the Qlik Sense Desktop April 2020 Patch 4, then try to open your exported app using that version. If not, then try with a later version. 

If you're able to open the published version,  then you could try to fetch the script from prod app using the Add Sense chrome extension. It is a quick tool where you can get a view and download the script of an app. 

You could also try the above suggestions on a copy of the source file, the source is found under the Apps subfolder in you installation QlikShare. It is named with the app_id and has no file type indicator. Make a copy of it and rename it by addin a .qvf in the name.

QMC->Apps->Edit App->(On the right)->App Objects  and App Content

You need to be owner of the the app to see the details.

Hi, I haven't done myself but another option could be using APIs: Qlik Sense: How to export app scripts - Qlik Community - 1717436

If it's just the script you're after you can extract the script from the script log file using the Reload Log Viewer in  QSDA Pro. You can use the Reload Log Viewer function without a QSDA Pro license. Download and install QSDA pro. Use the menu Utilities > Reload Log Viewer and select your logfile. (You can download the scriptlog from the QMC Tasks View).

In the Viewer the Extracted Script tab will show the script found in the log.

Thank you very much Rob. I gave up trying to open the app, so this was a very quick win.
