SweetAlert2: Please inlude Promise polyfill BEFORE including sweetalert2.js if IE10+ support needed.

This error occurs when running js enabled specs using poltergeist. I am not able to locate the error in code - possibly it is coming from the rails-assets-sweetalert2 ?

1. The word inlude is mispelled.
2. How can we inhibit this warning message, it's clogging up logs.

thanks!

I confirmed that this warning is caused by the rails-assets package.

Remove gem 'rails-assets-sweetalert2', '~> 5.1.1', source: 'https://rails-assets.org' from your Gemfile and include the sweetalerts2 assets in your project directly. https://github.com/limonte/sweetalert2/releases

I am not able to locate the project for rails-assets-sweetalert2 package, not sure who or where it is maintained.

PhantomJS is now deprecated in favour of Chrome Headless:

@vanboom, I found the solution with phantomjs.

You just need to include es6-promise pollyfill, https://github.com/limonte/sweetalert2#usage. It will fix the problem. If you want to see the source of rails-assets-sweetalert2, run bundle show rails-assets-sweetalert2. I'm using the lastest version of sweetalert2. It looks okay for me.
