I have a Python script that collects the information from the database and returns it via JSON (as described in the Zabbix manual), but when I go to my Host linked to the template, it gives the message that the value is not JSON. ...
My LOG does not contain error or failure, my script runs local and via zabbix_get returns the JSON that is validated in JsonLint
