In order for the short /raw/$token URLs to work, the app must be added to an array in the core code from the server. This change has already been implemented with this PR, but it will take until the next server point release for this change to arrive in the server core code.
Until then, an alternative setup was designed to work with longer urls. Unfortunately the alternative setup (without patching) doesn’t work correctly in this case. I am working on a fix. So the only working solution right now is the patch. How this must be done in “All-In-One” and Docker can be found here: Readme-aio
