Agents unable communicate with OCS Server

Hello!

OCS server version 2.4 installed on CentOS 7. Detail: PHP:5.4.16, Apache/2.4.6 (CentOS) PHP/5.4.16 mod_perl/2.0.10 Perl/v5.16.3, MySQL Community Server version 5.7.21

Windows Agent: ver. 2.3.1.1 without any plugins

After inventory attempt I see errors in /var/log/httpd/error_log:

[Fri Feb 09 13:03:11.631322 2018] [perl:error] [pid 1547] [client <ClientIP>:4007] Can't call method "do" on an undefined value at /usr/local/share/perl5/Apache/Ocsinventory/Server/System.pm line 189.\n
