Cannot create asset.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEditor.SceneTemplate;
5. using UnityEngine.SceneManagement;
6.  
7. public class NewBehaviourScript : MonoBehaviour
8. {
9.     public string test = "hello";
10.     // Start is called before the first frame update
11.     void Start()
12.     {
13.         SceneTemplateService.CreateSceneTemplate(test);
14.     }
15. }

That's my script, I append it to a cube, press play and I get this error message:

Code (CSharp):

1. UnityException: Creating asset at path champ failed.
2. UnityEditor.SceneTemplate.SceneTemplateService.CreateTemplateFromScene (UnityEditor.SceneAsset sourceSceneAsset, System.String sceneTemplatePath, UnityEditor.SceneTemplate.SceneTemplateAnalytics+TemplateCreationType creationType) (at <49dd6fba630a4485a2d84fe09bd6a4a6>:0)

Never used this API but pretty much every other editor asset creation API in Unity requires that you tell it the full path, which would probably be prefixed with

"Assets/"

and suffixed with

".unity"

Did you try using a string such as

"Assets/FoobarDoodle.unity

?
