There are no data sources in the app I uploaded to the cloud hub
I uploaded an app to the cloud hub, but all the attached files and data connections have been removed from the app.
Possible cause
Exporting and uploading an app removes the attached files and data connections from an app.
Proposed action
Reattach these files and reconfigure the data connections for the app.
Error message: The visualization failed to render
When I uploaded my app to cloud hub, the error message The visualization failed to render displayed on one or more visualization objects in my sheets.
Possible cause
Your app may be from an unsupported version of Qlik Sense. Apps must be from Qlik Sense 3.1 or later.
Proposed action
Update the app to a more recent version of Qlik Sense by updating the Qlik Sense deployment. You can also import the app into a more recent version of Qlik Sense and then export the app again.
Error message: Invalid visualization. The extension is not available in the cloud
When I uploaded my app to the cloud hub, the error message Invalid visualization. This visualization was not found. The extension is not available in the cloud displayed on one or more of my extensions.
Possible cause
You uploaded an app that contained an unsupported extension. Qlik Cloud Services only supports extensions from the Dashboard bundle and Visualization bundle.
Proposed action
Remove the invalid extensions from your app. To find out which extensions are valid, see Creating apps in the cloud hub.
My app failed to export
When I tried to export my app, it failed.
Possible cause
Your app may use section access for security in the data load script.
Proposed action
For security reasons, exporting apps that use section access is not permitted in the cloud hub.
