Bug when using spine with animated sprite?

Phaser 3
1

I think I’m stuck in this bug.
When I load spine data:

this.load.setPath('client/assets/');
this.load.spine('skeleton', 'skeleton.json', 'skeleton.atlas');

Then whenever I play an animation created by:

this.anims.create({ key: 'animKey', frames: this.anims.generateFrameNames('myAnimation'), repeat: -1 });

Then I get this error:
TypeError: animationFrame is undefined

I tried to reset path after loading spine, but the bug still there.
By the way, are you guys using any bone animation engine (or code library) with Phaser 3? I’ve been struggling to get Spine to work with Phaser 3…
Thank you.
