Hello! when i wanna set object like parametr collision get error

Uncaught TypeError: Cannot set property ‘gameObject’ of undefined

My example code look like this:

this.load.json(‘shapes’, ‘assets/shapes.json’); // initialize fun
this.load.atlas(‘sheet’, ‘assets/atlas.png’, ‘assets/atlas.json’);
var shapes = this.cache.json.get(‘shapes’); // create fun
var ground = this.matter.add.sprite(0, 0, ‘sheet’, ‘background’, {shape: shapes.background});

Object is created via editor, here is my code of json object { "generator_info": "Shape definitions generated with PhysicsEditor. Visit htt - Pastebin.com

Where is problem?

I have solution, must uptade Phaser to 3.16 from 3.8 because object adding by matter.add.sprite not have a “centerMass”.
