Error while generating task.

The text on the video is not in English, but I think that's beside the point. In the generator, I indicated in which language to generate the text and that a new point was needed “POI”. Saving fails due to the lack of a scene, as I understand it, and when I turn on the scene, an error occurs. Maybe I misunderstood something. Is there a solution or can someone tell me what I did wrong?
