Installing schedy - Unable to find module schedy_heating - initialize() skipped

Hi guys, noob schedy/HA user here…
I run HA on a VM and works well.
Managed to install appdaemon today, looks from my log that hello world works fine.
Added “hass-apps” to python-packages in the appdaemon config tab.
Created apps-loader file and saved that in the apps folder with this info

# This is just a stub which makes the app classes available for AppDaemon.

from hass_apps.loader import *

Schedy tutorial followed but log giving this error after doing a update to schedy.yaml file:

My schedy_heating.yaml

chedy_heating:  # This is our app instance name.
  module: hass_apps_loader
  class: SchedyApp

  actor_type: thermostat

Thanks.

The issue was a blank space ; " hass_apps_loader.py" . Removed that and I’m now a step closer to schedy than i used to be.
