Jquery and Prototype Conflict in Rails Production

Question

I am using Stripe to submit payments - it has been working in development and production, but after pushing recently I noticed there is a javascript conflict, which prevents stripe from creating the stripe key and processing the payment.

I have a problem I cannot seem to solve - I am using both jquery and prototype, and understand to use the below to avoid the conflict:

var $j = jQuery.noConflict();

I have removed most of the console bugs, but one remains that I cannot remove:

Uncaught TypeError: Object [object Object] has no method 'attachEvent' application-adc689800dc4b504f7b6a94f201ed3c1.js:268
m application-adc689800dc4b504f7b6a94f201ed3c1.js:268
(anonymous function) application-adc689800dc4b504f7b6a94f201ed3c1.js:268
(anonymous function) application-adc689800dc4b504f7b6a94f201ed3c1.js:268

This points me to application.js, which includes the following:

//= require jquery
//= require jquery_ujs
//= require bootstrap
//= require prototype
//= require prototype_ujs
//= require effects
//= require dragdrop
//= require controls
//= require_tree .

Does anyone have some suggestions on things to try? Any help would be much appreciated. Thanks!
