When restarting the services for Qlik Sense Enterprise, bundled extensions disappear from the system. The files are missing from the service cluster extension folder and the apps that use those extension are now showing problems. Reinstalling the extensions works, but at the first reinstall, they get removed again.
Environment
Resolution
This usually happens for obsolete extensions that are no longer supported in the current version of Qlik Sense Enterprise. Usually, the functionality of these extensions was replaced by product features. So, apps should be redesigned to use the new features, in order to have a fully supported functionality.
If they are needed for a transition period, following the following steps will prevent the automated deletion.
- edit the .qext file for each of the affected extensions (they are in the Service Cluster Folder --> StaticContent ---> Extensions ---> folder name of the extension )
- replace the line:
"installer": "QlikExtensionBundler"
with
"installer": "none"
By doing this, they will not be detected as unsupported extensions, and therefore not removed.
