Help! I cannot upload a tmj file For tilemap Collision on Event, but i can upload it directly on Tilemap Collision Object


It work fine through the tilemap object mask

help i dont understand, i’m trying to use a tilemap collision mask and i want to be able to change it through Event.
Should i consider it as bug or its just my mistake?

Note: From the Tiled Program i upload the Tilemap To json but what i got is tmj.
