Hi Jared,
Sorry for the inconvenience caused.
The outdated ej2.min.js file was incorrectly updated in CDN link on August 22, 2019, and now we have refreshed the CDN with the latest changes from our end. With the refreshed script, the reported console error would have been fixed automatically, so we suggest you clear the browser cache and run your application.
Regards,
Suriya M
