Error 404 for temporal grouping details
When you select temporal grouping details for an event group, an error is displayed.
Problem
When temporal grouping details are selected for an event group, the following error is displayed:Error 404: Hmm, we can’t seem to find that.This error can be caused by deleted policies. Policies are created based on historic event data in a Cassandra database. This historic event data is kept for 90 days. If event evidence for an existing policy is no longer found, the policy is deleted. Sometimes, this deletion can happen while events are still present in the ObjectServer, which were grouped based on the deleted policy. Therefore, the policy can no longer be found when you click the temporal grouping icon.
