Update message error

Update the message error returned in the API when deploying a scene to the Genesis City with the `worldConfiguration` config present in the scene.json

Start by locating the API path that deploys a scene to Genesis City and handles a scene.json containing the worldConfiguration config. Confirm the current returned error message and update it to the wording intended by the issue; done means the API returns the corrected message for that case.
