Why rsync command is failing with error "rsync error: error starting client-server protocol (code 5) at main.c(1656) [Receiver=3.1.2] [Receiver] _exit_cleanup(code=5, file=main.c, line=1656): about to call exit(5)" ?

Issue

• While executing rsync to share file from a source to destination system we encounter the following error:

  [root@example ~] # rsync -vvv -az -e ssh root@test::file_name /path
  opening connection using: ssh -l root test rsync --server --daemon .  (8 args)
  sending daemon args: --server --sender -vvvlogDtprze.iLsfxC . file_name/  (5 args)
  @ERROR: invalid parameter           # This is the parameter for the file
