Youtrack custom widget failing

We are self-hosting YouTrack and I am following the documentation to create a custom widget. I have been able to successfully test the widget in the widget playground. When i upload the custom widget as a zip file it successfully uploads, however when i add the widget to my dashboard the widget does not render. I can see in the network tab that the request for the widget javascript is being sent to https://<my_domain>/index.js however i note that other widgets are sending the request to https://my_domain/hub/api/rest/widgets/quick-notes/archive/main-24f8fae6a61132a6c664.js 
 

how can i get the widget to render?

my zip file has the following structure

./dist
├── manifest.json
├── index.html
├── index.js
└── index.css

here is my manifest.json

  "key": "milestone-widget",
  "version": "1.0.7",
