On-demand App Generation (ODAG) error: Users can no longer view sheets in applications.

Users can no longer open sheets in a Qlik Sense application after they upgrade to Qlik Sense June 2017 version. All applications, including newly created ones, are affected. 

The message: On-demand app error is displayed.

Environment:

• Qlik Sense Enterprise June 2017

 

A new service was introduced with Qlik Sense June 2017: "On-demand App Generation" (ODAG)
This will also create new sub folders in the application data folders. 
During the upgrade, the Qlik Sense service account permissions may not have been correctly inherited for the new folders. 

To resolve the problem re-apply inherited permissions on the C:\programdata\Qlik\  folder for the user running the service.
See screenshot illustration below;




Another problem we have seen is in this location C:\Program Files\Qlik\Sense\OdagService; where the OdagService files are missing on this folder most probably because of permission problems, and the way to fix it is to perform a reparation with an Admin account and the files should be recreated.
If this does not fix the problem then most probably the OdagServiceSettings and OdagServices tables are empty in your Repo DB, Please contact Qlik Support to re add those values.
