Nagvis: Trying to access array offset on value of type int

[AirBank_HD]

Hi, I updated nagiosxi to 5.8.7 and php to 7.4. After the update I can't create a new map. Where could be the problem?
OS: CentOS 7
PHP: PHP 7.4.25
Nagiosxi: 5.8.7
Nagvis: 1.9.8

Code: Select all

Error: (0) Trying to access array offset on value of type int

HI,

Welcome to the Nagios Customer Support Forum!

It looks like you are hitting the issue below after the upgrade.

Fix: php7.4 Trying to access array offset on value of type int

Please try making the proposed change to the GlobalMapCfg.php in the following directory.

Code: Select all

Thanks! I changed the GlobalMapCfg.php lines

Code: Select all

if($id[0] == '_')
     $todo = true;

to

Code: Select all

if($id !== 0 && isset($id[0]) && $id[0] == '_') {
            $todo = true;
        }

Nagvis started working.
