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.
Everything seems to be fine on my machine.
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.
Ah, OK then :)
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.
I've found that picture math is produced for some math in your file. It is caused by using $$ ... $$ instead of \[ ... \]. I think that I was not able to output verbatim math input for $$ math, so it is not like I forgot to add support for it. At least I think.
