Thumbnails broken in CP after migrating images to AWS S3 I migrated my images over to AWS S3 using the Amazon S3 plugin; however, now I'm seeing that the thumbnails in the CP are broken, and a brokenimage is displayed.



The full size images display fine in the CP and the front end. If I re-upload them, the thumbnails display correctly in the CP, but that's not an ideal solution.

Is there a way to make the images display correctly in the CP without re-uploading them?
My first guess would have been that the asset indexes stored in the database are out of sync since it was recently migrated to a new Volume.

A way to fix that would be to run the "Update Asset Indexes" utility from the Control Panel.
