Extension bundle not working

App Developers Designer Extensions
1

Hi, I’m developing an extension. It’s working successfully during testing on localhost:1337, but after uploading the bundle, nothing is being displayed. Also, the designer extension URI is responding with a 404 error.

Two possible reasons:

  1. Can you confirm that the code and all needed resources are inside the publicDir directory defined in the webfow.json manifest
  2. Do you have any resources referenced using absolute paths? When you upload a bundle, we serve each bundle from a path that has a unique bundle sub-directory (Eg. https://<app prefix>.webflow-ext.com/<bundle hash>/index.js). If you’re referencing any resources using the absolute path syntax (eg. /scripts/app.js), it won’t work on the uploaded version because we serve it from that bundle-specific sub-directory
