what (code=exited, status=1/FAILURE) ? service nginx status

I just found an error in the state of nginx. This error does not prevent anything. It does not give me problems. Everything is started correctly. Nginx -t It did not return any syntax errors.

I only see it in the nginx status sale. Service nginx status. Or Systemctl status nginx

Error:

systemctl status nginx
