We have deployed a jss app to a Content Delivery server.
We have followed instructions to add jss support to the server role.
Links to media items generated by Image components begin with /-/jssmedia and 404.
Changing the generated urls to start with /-/media makes them serve an image.
The error in the logs for broken links is this:
3392 11:43:27 ERROR Application error.
Exception: System.Web.HttpException
Message: The file '/-/jssmedia/cms-sitecore/data/media/img/sitecorejss_media.ashx' does not exist.

IIS Handler Mappings
On the Content Delivery server, IIS Site > Handler Mappings shows the sitecore_media.ashx endpoint. It does not have a sitecorejss_media.ashx endpoint.
On a Content Management server, where the images are showing up, the sitecorejss_media.ashx endpoint is registered.
