j2xParser.parse throws error if value is null

[sigoden]

var Parser = require("fast-xml-parser").j2xParser;
new Parser().parse({ value: null })

error:

@amitguptagwl - question
I have this XML:

<svg xmlns="http://www.w3.org/2000/svg" width="100" height="36" viewBox="0 0 100 36">
  <title>Some</title>
  <path d="M15.06,5.6a15.07,15.07,0,0,0,0,30.13Z" fill="red"/>
  <path d="M15.06,5.6a15.07,50.07,0,0,0,0,30.13Z" fill="blue"/>
</svg>

And I'm just transforming to object, and then transforming back to XML:

const parserOptions = {
  format: false,
  ignoreAttributes: false
};
const parser = require('fast-xml-parser');
const traversalObj = parser.getTraversalObj(xml, parserOptions);
const svgData = parser.convertToJson(traversalObj, parserOptions);

const Parser = new parser.j2xParser(parserOptions);
console.log(Parser.parse(svgData));

I'm getting

<svg xmlns="http://www.w3.org/2000/svg" width="100" height="36" viewBox="0 0 100 36">
  <title>Some</title>
  <path d="M15.06,5.6a15.07,15.07,0,0,0,0,30.13Z" fill="red"></path>
  <path d="M15.06,5.6a15.07,50.07,0,0,0,0,30.13Z" fill="blue"></path>
</svg>

I was expecting to receive self-closed tags for the <path />s.

How can I do it?

Thanks!

@csantos1113 if you check README, you 'll find following property to use at the time of parsing back;

supressEmptyNode : If set to true, tags with no value (text or nested tags) are written as self closing tags.
