Why can't I compress a string in Node.js

Using the following code:

const zlib = require('zlib');
const rawData = 'Hello World!';
zlib.deflateSync(rawData);

I'm getting the following error message:

  const isDuplex = this instanceof Stream.Duplex;
                        ^

TypeError: Right-hand side of 'instanceof' is not an object

    at Module._compile (internal/modules/cjs/loader.js:1063:30)
    at Object.Module._extensions..js (internal/modules/cjs/loader.js:1092:10)

How do I resolve this error message?

Please try to assign result to value named data.

const zlib = require('zlib');
const rawData = 'Hello World!';
const data = zlib.deflateSync(rawData);
console.log("result is ===>", data);
