Problem Description

Hi there. Since recent updates TheHive began to hide observables on UI (the value is not visible, but tags, description, reports etc seem fine). When we search for their value, we get the right output (value is still empty in the UI though).
It seems like TheHive fails to get values of observables and display them on the interface.

Using Browser Devtools, I found that the

that should contain the observable value simply does not exist at all on a case where observables are missing.

This problem also affects alerts randomly.

Which component would be responsible of this bug ? Would a migration of cassandra + elasticsearch data to a fresh TheHive installation fix the problem ?

Steps to Reproduce

1. Create a Case with fewx observables
2. Wait for a few days
3. The existing Case will have observables missing

Possible Solutions

Fresh install of TheHive component only ?
