No problem. Thanks for trying. Could you please try this? Compile to PDF first
using lualatex content_all.tex and leaving all temporary files generated
as is in the folder.

Now please try compiling to HTML using the same command I have in
that text file and see if you get an error.   I found  on my end,
if I do not clear all temporary files from the lualatex compilation before
starting the HTML compilation, sometimes I get  this error. But if you do
not, no problem, just something to try.

But my makefiles are set the same way for all my tree. They use
the same make4ht command. So I have no idea when I run make if
I have added a new section or not anywhere in some
latex file. Since they need to work on any folder and any where. So I
I can't really hard code the draft option.

I do not use svg anymore for math. I assume you are talking about math here. I
use  mathjax now. For graphics images, I convert all my images to SVG using
makefiles automatically from PDF files, before compiling latex to HTML. I have
not used SVG for math for long time now.  Sorry if I misunderstood you.
