Cannot read property 'childNodes' of null about mathjax-node

"This specific snippet cannot be parsed" does not sound like a mathjax-node message.

In any case, the following works for me, e.g., try it on https://npm.runkit.com/mathjax-node

var mjAPI = require("mathjax-node");

mjAPI.typeset({
  math: ' \\begin{align} \\xrightarrow{\\alpha}&\\quad \\tag{01} \\end{align}',
  format: "TeX",
  svg:true,  
}, function (data) {console.log(data.svg)});

@pkra ok thanks for confirmation
this snippet is actually a simplified version of something way more complex from our system.
but yeah, after checking that TeX string very very carefully, mathjax-node actually can render it (after fixing some escape issues).
and now I have to check upper layers of our processing pipeline since mathjax works great.

thanks

Thanks for confirming. Glad to hear you could work it out.
