sync connection, the files are created, but my app reports HTTP 419 “This page has expired”.database connector instead, but this requires a worker to be running to process the jobs. Now fly.io is designed to use a separate process for such tasks. However, the volumes available on fly.io can only ever be connected to one of the processes (or machines in the background). This means that when exporting with the queue, the export files are created correctly on the worker storage and I even receive a notification in my app. But of course I can't download them in the app because they are on the worker storage.
