FBX animation works on Unity, Autodesk viewer but not on threejs

Hi There!

Any reason why a simple animation might not be working on Threejs?

FBX Loading

const loader = new FBXLoader();

  loader.load('/Brickz.fbx', (fbx) => {
    //play Running animation
    const mixer = new THREE.AnimationMixer(fbx);
    animationsMixers[fbx.uuid] = { 
      mixer: mixer,
      animations: {}
    };
    
    for (const key in fbx.animations) {
      const animation = fbx.animations[key];

      if (animation.name === 'Armature|Running') {
        console.log(animation);
        animationsMixers[fbx.uuid].animations[animation.name] = animation;
      }
    }

    if (animationsMixers[fbx.uuid].animations['Armature|Running']) {
      const animation = animationsMixers[fbx.uuid].animations['Armature|Running'];
      const action = mixer.clipAction(animation);

      animationActions['Armature|Running'] = action;

      action.play();
      
    }

    fbx.scale.setScalar(0.01);
    fbx.position.set(0, -2, 0);
    fbx.castShadow = true;
    fbx.receiveShadow = true;
    fbx.traverse((item) => {
      if (item.isMesh) {
        item.castShadow = true;
        item.receiveShadow = true;
        item.material = material
      }
    });

    group.add(fbx);
  });

Animation loop

 const animate = () => {
    requestAnimationFrame(animate);

    const delta = clock.getDelta();

    for (const uuid in animationsMixers) {
      const animationMixer = animationsMixers[uuid];

      if (animationMixer) {
        animationMixer.mixer.update(delta);
      }

    }

    controls.update();
    composer.render();
  }

  animate();
