Waiting notification - PHP Error

Hi,

I'm trying to push a package to a client but it stays stuck on Waiting Notification.

Here is what appears on the httpd error log:

 PHP Warning:  count(): Parameter must be an array or an object that implements Countable in /usr/share/ocsinventory-reports/ocsreports/plugins/main_sections/ms_computer/ms_computer_views.php on line 128

OCS version: 2.5

Agent: 2.4

Php: 7.3.1

Perl: 5 version 16

MariaDB: 10.1.37

OS: Centos 7.3.16.11

Any help is most welcome.
