I want to use this npm package
window = {};
pm.sendRequest(“https://unpkg.com/[email protected]/image-to-base64.min.js”, (error, response) => {
var text = response.text();
(new Function(text))();

window.imageToBase64("https://images.unsplash.com/photo-1611270629569-948d94ca915a?ixid=MXwxMjA3fDB8MHxlZGl0b3JpYWwtZmVlZHwyfHx8ZW58MHx8fA%3D%3D&ixlib=rb-1.2.1&auto=format&fit=crop&w=500&q=60")
    .then(
        (response) => {
            console.log(response);
        }
    )
    .catch(
        (error) => {
            console.log(error);
        }
    )
});

But this didn’t work and shows me this error ReferenceError: module is not defined
I also tried this code
const imagebase64 = pm.environment.get(“imagebase64”);

(new Function(imagebase64))();

imagebase64("https://images.unsplash.com/photo-1611326758959-07fb4a250fcc?ixid=MXwxMjA3fDB8MHxlZGl0b3JpYWwtZmVlZHwyfHx8ZW58MHx8fA%3D%3D&ixlib=rb-1.2.1&auto=format&fit=crop&w=500&q=60")

this is also showing me this error SyntaxError: Unexpected token '}'

Please anyone help me with this

You need to use eval to run the code you have fetched from unpkg.com.

Here is a tutorial I did a while back demonstrating this concept.

I hope this helps. If you get stuck, let me know.
