WebGL partial glitch with armature baked action

Hi Yuri and dev team,

I recently discovered a bug in my verge app that is part of a rigged armature that seems to be broken in one part on the claw of the industrial robot arm. I am putting a video of how it should look from blender and a link to the actual application in development. Not really sure how to troubleshoot why that part of he rig isn’t coming into verge right when the rest of it works fine. Thanks in advance for your help.

PS – To view the animation in the verge app, you have to click on the word “availability” on the left and then an orange dot will appear that you can activate the animation.
