Users see the following error after logging into /designer:
The report you requested is invalid or no longer available.
The corresponding error in the application server log is as follows:
[http-/0.0.0.0:8080-1] ERROR com.appiancorp.process.analytics2.display.ReportCache - E106 com.appiancorp.kougar.driver.exceptions.Signal: E106
E106 is an internal code that denotes an invalid document. In this case, the OOB All Processes report that is displayed on navigating to /suite/designer had been deleted.
There are two options:
APPIAN_HOME>/_admin/_scripts
Deleting OOB content is not recommended and as such the best practice is to restrict access to these content so that they would be immune to deletions.
This article applies to all versions of Appian.
