Error restart flow-accounting

Hi guys,
I want to activate flow-accounting but i can’t cuz i received this:

Failed to start/stop flow-accounting
failed to run command: systemctl restart uacctd.service

I try to restart it manualy and it’s the same issue.
Into the journalctl the message is next one:
