Store App missing from Dev instance

MHager · 3 weeks ago

I am having an issue with a specific Service Graph Connector not being listed in the Application Manager in my development instance.

I installed the Service Graph Connector for Ordr, but was having some issues with the configuration, repaired it and then ultimately uninstalled it fully with the intent of reinstalling from scratch.

Now the connector is not listed in that instance as installable but does in my Test and Prod instances. What could cause this, and has anyone run across an issue like this before?

Hi @MHager

Can you try the resolution in your non-prod ( sandbox /dev) as mentioned in this KB:

KB3158800 Installed application not visible in Application Manager

Issue

An installed application is not visible in the ServiceNow Application Manager. Syncing the store and clearing the Application Manager cache did not resolve the issue.

Cause
A custom app entry for the application in the sys_app table prevents the store application from appearing in the Application Manager.

Resolution
Navigate to sys_app.LIST in the instance and delete any custom app entries for the affected application.
Verify that the application is now visible in the Application Manager after removing the custom entry.
Note: If the application is still not visible, a missing sys_app record may be the cause — for example, after an instance clone where sys_app was not preserved. Use the Convert to Development Mode link to regenerate the sys_app record, and add sys_app to the Clone Data Preserver table to ensure application metadata persists across future clones.
If the application remains unavailable, verify that the following sys_properties are configured correctly.
sn_appclient.app.install.offline — false
sn_appclient.repository_base_url — https://apprepo.service-now.com
sn_appclient.upload_base_url — (blank)
sn_appauthor.upload_base_url — (blank)
Note: If syncing the instance does not restore application visibility after an upgrade, a version mismatch between the application and the current platform release may be present. Use the ServiceNow Store to verify compatible versions for the application.
Reindex the affected tables (sys_package, sys_remote_app, sys_app_version) to ensure changes take effect. For reindexing instructions, see Reindex tables in ServiceNow — KB2805679.
Run the following script in the background script executor to clear the cache and sync the Application Manager:
new global.AppManagerCache().deleteAllCache()
new sn_appclient.UpdateChecker().checkAvailableUpdates();

6. Confirm that the application is visible in the Application Manager after reindexing.

Thanks for the suggestion and link to the KB! That did the trick, and now I have a new tool to use when/if this happens in the future.
