Mixamo Animation Failing on Examples Page

[ep5000]

Hi,
When attempting to load a Mixamo animation on the Examples page (https://pixiv.github.io/three-vrm/packages/three-vrm/examples/humanoidAnimation/index.html) the animation does not play and the following error is thrown in the JavaScript console:

hmm...
The error could not be reproduced with the "Body Block" animation.

What is the name of the mixamo animation that causes the problem?

I was using "Rhumba Dancing". I also tried with "Body Block" and received the same error in both Chrome and Edge. I'm downloading the FBX file from Mixamo as a binary FBX without skin, 30 or 60 FPS (both receive the same error):

Thank you for the details. I think the reason is that the names of the bones.
Please try downloading animations using the characters provided by mixamo (e.g. Y BOT).
