Additional context

I use API a lot from Powershell module. I tried using CURL in bash, same result.
In the current situation, I can not manage rules thru the API.
The goal is to automatically create location rules based on the IP. We use a external application to manage the thousands of subnets linked to about hundred different locations.

My humble feeling is that a declaration is missing somewhere but my php competencies does not allow me to dig deep :-/

Please test with latest stable.

I just updated to 9.4.4.
Same issue when I try to get "rulecriteria" objects.

Is there anything else I can do to help you guys get any idea of what happens?

[J-C-P]

GLPI Official support provided the solution.

Add
static public $itemtype = 'Rule';
before the line
static public $items_id = 'rules_id';
in both rulecriteria.class.php and ruleaction.class.php

Rules manipulation is now possible thru the API. I don't know if a fix has been submitted.
