Dynamic Tilemap Collisions Broken

[reactdev]

        this.map = this.make.tilemap({ key: 'map'})
        let tileset = this.map.addTilesetImage('tiles', 'tiles')
        let terrain = this.map.createDynamicLayer('terrain', tileset).setCollisionByExclusion([])
        this.playerSprite = this.physics.add.sprite(200,0,'players',0)
        this.physics.add.collider(this.playerSprite, terrain)
        this.cameras.main.startFollow(this.playerSprite)

This code has the effect of the player sprite falling through the terrain layer.

Why?

I've tried using setCollisionByProperty, setCollisionBetween, and setCollision. Nothing works. Using Phaser 3.22.

Solved with setCollisionByExclusion([-1]).

Apparently by default even empty tiles were colliding, meaning the physics engine basically turns itself off because a physics body was placed inside of a body it is supposed to collide with.
