Creating a place doesn't work and outputs HTTP 403?

I have "allow to use as template" and "allow to save" enabled, but it doesn't work.

THESE SCRIPTS ARE NOT LOCAL

local worldId = AssetService:CreatePlaceAsync("World", 8377452008)

When i use it on "Play" it outputs

Game:CreatePlace received and error: HTTP 403 (Forbidden).  -  Server

In game on the dev console this also outputs

Game:CreatePlace received an error: HTTP 500 (CreatePlaceConfiguration).

By the way, the place i'm copying is owned by a group.
