Display issue in the pannel to add entities to the knowledge of a report

[amr-cossi]

Description

In version 3 of OpenCTI, in the entity pannel of the knowledge part of a report, when an entity is selected to figure on the graph view, it is supposed to be ticked in blue (previous versions), but in the new version, it is not anymore ticked in blue when the pannel is opened, even though it is on the graph view. However, if you click on the entity in the pannel, an error message indicating that an entity with the same key already exists appears.

Environment

1. OS (where OpenCTI server runs): demo
2. OpenCTI version 3.0
3. OpenCTI client: demo

Reproducible Steps

Steps to create the smallest reproducible scenario:

1. Go in the knowledge view of a report.
2. Open the side pannel with the orange "plus" button
3. Search and try to add an entity already present in the graph

Expected Output

The entity should be ticked in blue, and clicking on it should prompt a dialog box to pop-up to ask for confirmation before suppression (see issue 499 on this)

Actual Output

The entity is not ticked in blue and a message of error appears when you try to click on it.
