API - 404 App Not Found

Hello,

I installed hass.io under docker
I installed Franck Nijhof’s appdaemon plugin (version 3)

I left the default configuration for HA dashborad and API ports (5050 and 5000)
below my file appdaemon.yaml (under /config/appdaemon):

secrets: /config/secrets.yaml
log:
  logfile: /config/appdaemon/log/appdaemon.log
  errorfile: /config/appdaemon/log/errorfile.log
appdaemon:
  threads: 10
  api_port: 5000
  app_dir: /config/appdaemon/apps
  plugins:
    HASS:
      type: hass
      ha_url: http://hassio/homeassistant
      token: XXXXXXXXXXXXXXXXXXXX
hadashboard:
  dash_url: http://127.0.0.1:5050
  dash_dir: /config/appdaemon/dashboards

My file apps.yaml (under /config/appdaemon/apps)

hello_world:
  module: hello
  class: HelloWorld

And my file hello.py (under /config/appdaemon/apps):

import appdaemon.plugins.hass.hassapi as hass

class HelloWorld(hass.Hass):

  def initialize(self):
     self.log("Hello from AppDaemon")
     self.log("You are now ready to run Apps!")

when I do a test with the command below

 curl -i -X POST -H "Content-Type: application/json" http://localhost:5000/api/appdaemon/hello_world -d '{"type": "Hello World Test"}'

I have the error

<html><head><title>404 App Not Found</title></head><body><h1>404 App Not Found</h1>Error in API Call</body></html>

below the logs when starting appdaemon and an API test

According to the logs, the API is started and the application “hello_world” is initialized.
I haven’t found a solution yet, that’s why I’m asking you;)

Thanks in advance and sorry for my English
