I am trying to parse the XML and query the content but I see an error xmldoc.querySelector is not a function, this error seems weird because, I only find it when I run my code on AWS Lambda( Node.js 12.x) but not when I run it on the online compilers like playcode.io. Please refer the following code.

const tmpl = 
 tmpl = `<doc>
    <request>
         <delta>         
         </delta>         
         </request>
</doc>`
const xmldoc = new DOMParser().parseFromString(
tmpl,
'text/xml'
);
let dest = xmldoc.querySelector('order')

ERROR MESSAGE -> "stack": "TypeError: xmldoc.querySelector is not a function

Any help on this will be appreciated.

Thank you!
