okay, so if i set set_default_upload_destination as URI that’s local to the computer running the task (and the server):

• the server is “unable to load the image”—not surprising because the filesystem URI was not mounted into the container
• the files are present at the expected location on the local filesystem, but they are…blank! all white.that tells me that report_media might have been successful, but there’s some issue …encoding the data to a jpeg?
