cannot get mailGraph running

[blackbasket]

Hi,

I set up mailGraph following this article (https://znil.net/index.php?title=Zabbix_mailGraph_installieren_-_Trigger_Alerts_Emails_mit_Grafiken). But now I am getting errors if I try to send a test mail using cli as well as WebUI.

CLI error:

PHP Fatal error:  Uncaught TypeError: sizeof(): Argument #1 ($value) must be of type Countable|array, true given in /var/www/html/mailGraph/mailGraph.php:885
Stack trace:
#0 {main}
  thrown in /var/www/html/mailGraph/mailGraph.php on line 885

WebUI error:

I do not find anything in the logs. The folder is still empty...

Hi, can you share the first lines of the log output that have the version of mailGraph and Zabbix?

[blackbasket]

Sorry for the multiple edits... I was in a hurry this morning... because of this there are some relevant information missing as well...

Debian 12
Zabbix 7.0 LTS
PHP 8.3

MailGraph was cloned this morning from GitHub...

MailGraph was cloned this morning from GitHub...

Just checked... the script starts with
mailGraph v2.16

Log output I cannot share because the folder is empty as mentioned...

I'm impressed by the arcticle --- will put a link in the README for it.

Have you cloned from my repo as the current version is v2.18 and I did make some changes related to referenced vars that were empty due to assumed values and outcomes?
Can you please update to v2.18 and verify if the issue arises still?

Yes, I have cloned 2.18 from the repo. In the script the first line is still "// mailGraph v2.16" ;)
