Appdaemon Warning: TypeError: argument of type 'NoneType' is not iterable

Any idea why this (see below) has been showing up a lot in my logs?

If I understand this correctly, it’s saying that config is None? In which case, would AppDAemon even work? (All my apps work as expected).

Warning that keeps popping up:

Take out sensitive parts of your config file and share it. Seems like it might have something to do with using the “secrets” keyword.

You mean just the appdaemon.yaml? It’s pretty minimal:

---
secrets: /homeassistant/secrets.yaml
appdaemon:
  latitude: REDACTED
  longitude: REDACTED
  elevation: REDACTED
  time_zone: REDACTED
  plugins:
    HASS:
      type: hass
http:
  url: http://127.0.0.1:5050
admin:
api:
hadashboard:

Changed /config/secrets.yaml to /homeassistant/secrets.yaml when addon configs moved to the addon_configs mount.

I’m not really sure which app this is coming from, I have a bunch of app config files split between “types” of things. But I just made a test:

test:
    module: test
    class: Test
    grocy_api_key: !secret grocy_api_key

and if I try logging self.args['grocy_api_key'] from test.py, I get the correct value from my secrets.yaml file.

EDIT: I noticed that when I added the test app, it looked fine. When I commented the config for the app in test.yaml, this appeared in the logs:

An update, in case this helps.

It seems to me like I get the warning about secrets whenever there is an app with it’s yaml config commented out, and that config contains a reference to secret (e.g., the test.yaml in the logs in previous post).

Does that explain this and/or is that expected? I thought it would just ignore apps with yaml commented out?

Yeah, commented YAML is not looked at so this doesn’t really make any sense.
