The only difference between loa3 v1 and v2 is the skeleton Joint, Segment, Site names.
In fact, John may have a version of this or close with V2 names, same skeleton as joeKick.
So true it is a legacy model but correct current LOA3 if names are updated.
Thanks,
Joe.

Don, there’s already a patch for the viewpoints field on SourceForge, many months ago I think. Apparently, it has not been applied.
For HAnimSite, viewpoints *is* valid. Somehow, I managed to wipe out my changes to the stylesheet:

John, when I run the X3D Validator from within X3D-Edit on this model, it reports the following diagnostics in the log appearing below. This is relatively short, as these things go, which is good. Running the model shows that it is pretty functional too. * X3D Example Archives: Humanoid Animation, Specifications, HAnim 1 Specification LOA 3 Animation
* https://www.web3d.org/x3d/content/examples/HumanoidAnimation/Specifications/HAnim1SpecificationLOA3AnimationIndex.html
Note the presence of the first meta error element in the schematron log, highlighted by me, which states that this model includes errors under our HAnim 2.0 tools (since it has been adapted from HAnim 1.0).
That same error notification is also evident from simply inspecting the model documentation,
* 11 (https://www.web3d.org/x3d/content/examples/HumanoidAnimation/Specifications/HAnim1SpecificationLOA3Animation.html#11) <meta name=' error ' content=' Legacy model, not valid as X3D4 HAnim version 2.0 since HAnim version 1.0 has significant differences and is no longer directly supported '/>
* https://www.web3d.org/x3d/content/examples/HumanoidAnimation/Specifications/HAnim1SpecificationLOA3Animation.html#11
Perhaps fixable in small steps, but please don't be surprised if you encounter errors as advertised. I do try to be generous in noting errors and warnings in meta tags for each model, when they occur, to encourage precise continued troubleshooting.
Your log looks like the same X3DJSAIL internal error repeated many times. The key to an issue report is conciseness, clarity and repeatability.
Well-defined issues (called "tickets" by SourceForge) are addressed when possible (concise, clear, repeatable) and maintained online at

Recommendation is to check archive HAnimV2 specification .x3d models by validating them with X3DJSAIL. There’s no need to run foreign code, just CommandLine.java -validate. See below for one to choose. You should be able to search for “Specification” in the email.
I do realize running validation on the whole archive takes a lot of time, my archive too, when I’m generating code. I recommend focusing on a single model.
For example:
java -cp ~/X3DJSONLD/X3DJSAIL.4.0.full.jar org.web3d.x3d.jsail.CommandLine -validate
HumanoidAnimation/Specifications/HAnim1SpecificationLOA3Invisible.x3d
It would be good to get another set of eyes on this, even if an error isn’t reported.
I am adapting my code not to call setContainerFieldOverride().
I do have some good news, I am re-adopting the x3d.py module for testing in addition to JRuby and GraalPy for X3DJSAIL. There are a few tweaks I had to make, but these were made to:
https://github.com/coderextreme/X3DJSONLD/blob/master/src/main/node/PythonSerializer.js
So I have improved Python code generation. The old PythonSerializerX3DJSAIL is now:
https://github.com/coderextreme/X3DJSONLD/blob/master/src/main/node/GraalPySerializer.js
I had to take a break and get some sleep.
Maybe eventually I’ll get to languages like Kotlin and Scala. I’ve only played with Kotlin on the command line.
Typically one would use json2all.js:
https://github.com/coderextreme/X3DJSONLD/blob/master/src/main/node/json2all.js
This is tuned to run in X3DJSONLD/src/main/shell

Interestingly enough, I did some X3DJSAIL (recently compiled) against a recent checkout of the HumanoidAnimation archive on sourceforge:
x3d / Code / [r37163] /www.web3d.org/x3d/content/examples/HumanoidAnimation (https://sourceforge.net/p/x3d/code/HEAD/tree/www.web3d.org/x3d/content/examples/HumanoidAnimation/)
I fully realize that I haven't checked the archives elsewhere (which might not be checked in).
Looking for something checked in. I'll try X3DJSAIL from the distribution website next.
