Check_MK Discovery Can not load Robotmk JSON data! (json.loads())

Hello.

I’ve attempted to install also on a Windows machine that I added to Checkmk by installing the agent with the Robotmk plugin. The same happens. Maybe I’m misconfiguring the agent?
I can see that I have the files:
C:\ProgramData\checkmk\agent\config\robotmk.yml
C:\ProgramData\checkmk\agent\plugins\robotmk.py

The file robotmk.yml contents are:

# Created by Check_MK Agent Bakery.
# This file is managed via WATO, do not edit manually or you
# lose your changes next time when you update the agent.

# This file is part of Robotmk, a module for the integration of Robot
# framework test results into Checkmk.

# ROBOTMK VERSION: v1.4.1

global:
  execution_mode: agent_serial
  agent_output_encoding: zlib_codec
  transmit_html: false
  log_level: INFO
  log_rotation: 7
  cache_time: 960
  execution_interval: 900
suites: {}

Comparing to your example on a blog post, my file is missing a lot of entries, like the robotdir: C:\ProgramData\checkmk\agent\robot, and in fact, I don’t have this robot folder. So I seem to have the same issue both on Windows and Linux.
Below is my config. Am I missing something?


Thank you.
