Private app javascript 404 error

[wmw]

I've successfully uploaded and installed a private app to Cloud. The app simply contains a few javascript-based utilities which are located in, e.g.: common_ui_util/appserver/static/js/close_div.js

I'm hoping to use these in the same way that I'm able to from an enterprise install where, from any other app context, I'm able to include the javascript in the simple XML, e.g.: 
<form version="1.1" script="common_ui_util:/js/close_div.js">

However, this isn't working for me in Cloud, and the console shows the script as 404. The console shows the path as: https://<subdomain>.splunkcloud.com/en-US/static/@<id>/app/common_ui_util//js/close_div.js

I've verified that the app is installed and that I have set permissions to read for everyone, and exported globally.

What am I missing here?

@wmw- Please try removing extra slash (path separator) at the front.

<form version="1.1" script="common_ui_util:js/close_div.js">

I hope this helps!!! If it does kindly upvote and accept the answer!!
