Not able to remove Spine on complete event of animation for PIXI version 7 and pixi-spine version 4.0.4

[MayankDhankhar]

I am not able to remove spine animation from PIXI.Container. As soon as i removeChild it, it throws an error.

Please help. Below is the code :

private testSpineAnimation(): void { const resource = App.loader.resources.gfx['dice_Anim_1to5']; const animation = new Spine(resource.spineData); this.allSpineAnims = []; this.allSpineAnims.push(animation); // add the animation to the scene and render... this.baseContainer.addChild(animation);

    if (animation.state.hasAnimation('animation')) {
        animation.scale.set(0.5);
        animation.position.set(152, 552);
        animation.state.addListener({
            start: () => {
                console.log("ANIMATION START");
            },
            end: () => {
                console.log("ANIMATION END");
            },
            complete: (entry: ITrackEntry) => {
                this.clearAndRemoveSpineAnimations();
            }
        });
        // run forever, little boy!
        animation.state.setAnimation(0, 'animation', false);

        // dont run too fast
        // animation.state.timeScale = 0.1;
        // update yourself
        animation.autoUpdate = true;
    }
}

private clearAndRemoveSpineAnimations() : void {
    for (let anim of this.allSpineAnims) {
        anim.autoUpdate = false;
        anim.state.clearTracks();
        this.baseContainer.removeChild(anim);
    }
}
