SyntaxError: Export 'default' is not provided by 'mailgun.js' when importing in a Vite + React project

[Fedevs]

Description

I'm encountering a SyntaxError when trying to import mailgun.js in a project created using Vite and React. The error message is as follows:

Uncaught SyntaxError: The requested module '/node_modules/.vite/deps/mailgun__js.js?v=68b1499c' does not provide an export named 'default'

This occurs when trying to import mailgun.js using the default import syntax:

Environment

Vite version: 5.2.0
React version: 18.2.0
Mailgun.js version: 10.2.1
Browser: Chrome 126.0.6478.127
Operating System: Windows 11

Expected Behavior

mailgun.js should be successfully imported without any syntax errors.

Actual Behavior

A SyntaxError is thrown indicating that the default export is not provided by mailgun.js.

import Mailgun from 'mailgun.js';

I'm getting the same issue in my SolidJS + Tauri project

Environment

Vite version: 5.0.0
SolidJS version: 1.7.8
Mailgun.js version: 10.2.3
Browser: Chrome 127.0.6533.73
Operating System: Windows 10

But using a dynamic import is a workaround for now:

let Mailgun: any;
import('mailgun.js').then(module => {
  Mailgun = module.default;
  initializeMailgun();
});

let mg: any;

function initializeMailgun() {
  const mailgun = new Mailgun(formData);
  mg = mailgun.client({
    username: "api",
    key: import.meta.env.VITE_MAILGUN_API_KEY,
  });
}
