Uncaught ReferenceError: module is not defined when importing polyfill script

Current behavior

Hi, I’m using sweet alert 2 in my project I use plain javascript I imported the library like this

<script src="sweetalert2.all.min.js"></script>

It just works fine in my browser. But I realized, that sweet alert 2 is a promise based library so I had to polyfil it. So I imported the polyfill script just like in the documentation

<script src="sweetalert2.all.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/promise-polyfill"></script>

But I got this error in my console

index.js:274 Uncaught ReferenceError: module is not defined
    at index.js:274

The library works fine, but I’m just wondering if this error cause the polyfill script doesn’t work so the older browser can’t use the Promise feature that this library use

Expected behavior

No errors, works fine for older browsers

@dytra you are importing the wrong file from the promise-polyfill. As per the README, you need to use:

<script src="https://cdn.jsdelivr.net/npm/promise-polyfill@8/dist/polyfill.js"></script>
