"Spine hierarchy missing elements please map chest" but no mapping or rig option PLS HELP vrm file

Does anyone no how to fix this?
I imported a vrm file from vroid and used the correct method to convert for vrchat. When going to upload i get this error. I have looked all over the internet to find a answer but they all say to select model and rig. These options are not showing up for me. I sourced my avatar from vroid hub. Thanks in advance!
