Hello William, 
Thanks you for your reply, 

I can't share the whole output as it includes the whole document, but using 
the verbose option it proved my theory, 
that it do print the html file after generating it, thanks for the tip.

no obvious error messages and the here is the command passed to wkhtmltopdf 
``` wkhtmltopdf "--margin-bottom" "1.2in" "--margin-top" "1.25in" 
"--margin-right" "1.25in" "--margin-left" "1.25in" 
"--enable-local-file-access" "./html2pdf1272404-0.html" 
"./html2pdf1272404-1.pdf"
then the TOC in the html is like so 
 ``` 
<nav id="TOC" role="doc-toc">
<ul>
<li><a href="#introduction">Introduction</a>
<ul>
.
.
.
</ul></li>
</ul>
</nav>
``` 

then the reset of the pdf and the last couple of lines are 

```
Loading page (1/2)
Printing pages (2/2)                                               
Done                                                           
```

I am not sure if that enough for analysis, but I will also try to analyze 
it later, will go with weasyprint for now.

Regards, 
George
