Avatar Validation failed- Send help

ello, I have an issue with unity where I can’t upload an avatar made by a creator. It keeps showing me these errors and I don’t know how to fix it at all. At first it was the Blueprint id which somehow i managed to upload one of the avis. But now that i want to edit it just won’t work anymore. Now it’s this.

Mind you, i’m kinda new to all of this so i’m just beyond confused.

Spine hierarchy missing elements, please map: Chest

What does your skeleton rig look like for the FBX?

Here’s a valid humanoid rig:

Per Rig Requirements, you need a chest bone mapped to a humanoid rig for VRChat, even while it’s shown (incorrectly) as optional in Unity Editor.

it still keeps giving me those errors even after I fixed the chest

Make sure you are using VRChat SDK 3.9.0 or later.

nevermind i managed to somehow fix it and it worked, but thanks regardless for this extra helpful thing!
