Description:

For multiple drones scenario(look at the above image) when drones are dragged and dropped on the CesiumMap gives the below error:

Changes should only go in frontend/src/components/Configuration/MissionConfiguration.jsx

Changes might revolve around the below part of code in the same file as that relates to the multiple drones creation:

Acceptance Criteria:

• Ensure that the functionality is consistent.

Reason:
Integrate the functionality to support real-time environment updates for the Drag-and-Drop functionality in the Cesium 3D map.
