Description
Syncing files from the local folder to the server fails.
The client logs show:

I have downloaded the binary for linux (fedora in this case), and am running the latest server on docker. I have exposed both the standard port (9090) and grpc port (9091). TLS is turned off as I'm testing locally. Also, the web client works, including uploading files. (I have not tried the mobile client yet)
The ./cells-sync start starts normally. Connecting to the server works, setting up the sync task works. Files are successfully downloaded from the server into the sync folder.
It is only when the client tries to upload files from the local sync folder to the server that this error occurs.
From the error it seems like the PUT request isn't attaching the body. It says "Body length 0", which seems wrong.
Is this a bug? or am I just doing something wrong?
