I am using Ubuntu 24.04 LTS. When I am trying to start GridDB server it starting the server on WSL Without Systemd using the following command.

gs_startnode -u admin/admin

It is showing me the following error:

Traceback (most recent call last):
  File "/usr/bin/gs_startnode", line 87, in <module>
    pid = util.getpid(pidfile)
          ^^^^^^^^^^^^^^^^^^^^
  File "/usr/griddb-5.3.0/bin/util.py", line 191, in getpid
    fp = open(path, 'rU')
         ^^^^^^^^^^^^^^^^
ValueError: invalid mode: 'rU'

I have using python 3.12.3.

Any suggestion will be appreciated.
