I also put a sanitize node in and it completes fine and shows it works as it's replacing the fonts with default. I saw some font errors on first attempts so just went back to your toolbox and ran a sanitize and hit all the params.

Awesome tool when it works and could be super powerful for some things like this but curious why it fails...I ran it through o1 and it was pointing to a pure number input being passed as a string but I can't see it so...

Any thoughts would be greatly helpful and thanks.
