Hello

This MWE compiles OK with lualatex but fails in tex4ht using TL 2019 on Linux

--------------------------
\documentclass{article}%
\usepackage{amsmath}
\usepackage{adjustbox}
\begin{document}      

\begin{equation*}
\adjustbox{max width=\textwidth}{%
$ 
\begin{aligned}
y \left( x \right) &={x}^{2}+x+3\\ 
\end{aligned}
$}
\end{equation*}
    
\end{document}
------------------

Error is

'htm,3,pic-align,notoc*,p-width,charset=utf-8,svg' '-cmozhtf -utf8'
