I have installed R Studio Server on my Debian 10 VPS and started it as root. After i connected to the site and logged in, it showed this:

If I start it it also says
"TTY detected. Printing informational message about logging configuration. Logging configuration loaded from '/etc/rstudio/logging.conf'. Logging to '/var/log/rstudio/rstudio-server/rserver.log'."
but the log file does not exist.
