No problem when I run zabbix-cli from shell or via cron. But when I create External check in zabbix, I've got an error

Traceback (most recent call last):
File "/usr/local/bin/zabbix-cli", line 4, in

Thanks for the feedback.

This happens because we use the os.getenv('HOME') function to get the home directory of the user running zabbix-cli.

If the HOME environment variable is not defined, the code will raise an exception.
We have to check that HOME is defined before trying to use it.

Usually, processes startet e.g. with systemd do not have all environment variables as in a shell, per default. This can be a problem when running zabbix-cli as an external check if you want to use a configuration file under the $HOME directory of the user running the external check.
