OME not working

[artemoz2021]

Hello, what i've got: ansible 2.10.8 python 3.8.2 or 2.7.16 Target server: PowerEdge R740xd Target iDRAC firmware: 4.40.00.00

I'm trying to power off server remotely via ansible but the target machine reports with error. I've tryed to use module from collections and master branches, i've also tryed to use different version of python but with no luck.

This is a part of my test playbook:

The first task works correctly (get inventory) but the last isn't

tasks:
  - name: get device info
     ome_device_info:
       hostname:   "{{ server_ip }}"
       username: "{{ user }}"
       password:  "{{ pass }}"
     register: devinfo

  - debug:
      var: devinfo

  - name: power manager on
     ome_powerstate:
       hostname: "{{ server_ip }}"
       username: "{{ user }}"
       password: "{{ pass }}"
       power_state: "off"
       device_service_tag: "{{ device_svc_tag }}"

The erorr message that i've got (the same with python3):

An exception occurred during task execution. To see the full traceback, use -vvv. The error was: ValueError: No JSON object could be decoded

Please help, i don't understand what the purpose of this error.

@artemoz2021, ome_device_info and ome_powerstate are OpenManage Enterprise (OME) Ansible Modules. These modules work with OME only. If you want to run a workflow on iDRAC directly, then you must use modules that are prefixed with idrac_ or dellemc_idrac_ or redfish_. For e.g. the iDRAC modules for getting system inventory and performing powerstate operations are idrac_system_info and redfish_powerstate respectively.

Could you please confirm whether you are running the modules with OME or iDRACs?
