Entity is not a prefab instance

A prefab-only operation or nested entity address was used on a plain record. The command is rejected. A plain record carrying overrides or removed also fails document validation.

#Common causes

• prefab.override.set or prefab.override.revert targeted an ordinary entity.
• A slash-separated address starts with an entity that has no prefab reference.
• Prefab-only fields were left on a plain record.

#Fixes

• Use ara do property.set for an ordinary entity, or target an actual instance created with prefab.instantiate.

• Run ara check --fix <file> to remove overrides or removed when the diagnostic offers that repair for a plain record.
