ReactJS.NET ReferenceError: TextEncoder is not defined

I created a ReactJS.NET project using the reactnet-webpack template, then upgraded it from React 16 to the latest v18. However when I try to run the out of the box example I get the following error:

   ReferenceError: TextEncoder is not defined
     at eval (<anonymous>:145:19) -> var textEncoder = new TextEncoder();
     at eval (<anonymous>:7002:5)

How would I go about resolving this?

There are two ways you can try it：

First, Run npm install util, and use this code:

var util= require('util');
const textEncoder = new util.TextEncoder();

Second, Try by running npm install text-encoding.

and paste this code wherever it gives you the error:

const TextEncodingPolyfill = require('text-encoding');
Object.assign(global, {
  TextEncoder: TextEncodingPolyfill.TextEncoder,
  TextDecoder: TextEncodingPolyfill.TextDecoder,
});
const textEncoder = new TextEncoder();

Hope this can help you.
