"Empty String" error message

Unity Engine

I’m getting this error

Cannot load scene: Invalid scene name (empty string) and invalid build index -1
UnityEngine.SceneManagement.SceneManager:LoadScene(Int32, LoadSceneMode)
Movement:Update() (at Assets/Movement.cs:63)

On this line of code: SceneManager.LoadScene(SceneManager.GetSceneByName("Game Over").buildIndex, LoadSceneMode.Additive);

Why not just load your scene like this:

SceneManager.LoadScene("Game Over", LoadSceneMode.Additive);
