Error in core when trying to register hacs about integration HOT 8 CLOSED

Hello
This seems indeed to be related to constant_modifier which loads very early during startup. Its not really an integration, but a custom component that I use to modify some hard coded ZHA device timeouts for Aqara sensors since I did not get that to work with ZHA quirks.

I disabled the component and had no further errors on 2 restarts. Since that component is not maintained anymore, I'll have to see what to do with it and need to start research again how to reduce the ZHA device sensor timeouts otherwise...

Thanks for you assistance, I think this HACS issue can then be closed.

Make sure you have read the issue guidelines and that you filled out the entire template.

If you have an issue identical to this, do not add comments like "same here", "i have this too", instead add a 👍 reaction to the issue description. Thanks! 👍

Post a diagnostics bump file for any integration

Here is the HACS diagnostic dump file

I really think it is a timing problem during restart. Today there was no problem during one restart, but again on another restart. The HACS reload once all is started never failed.
I assume the hass object has not created the hass.data['integrations'] entry yet when HACS is querying it?
File "/usr/src/homeassistant/homeassistant/loader.py", line 1307, in async_get_loaded_integration
cache = hass.data[DATA_INTEGRATIONS]
~~~~~~~~~^^^^^^^^^^^^^^^^^^^
KeyError: 'integrations'
So maybe a delay must be introduced, or proper error handling when hass.data.get(DATA_INTEGRATIONS) is None

It is not HACS that is requesting it, that is core.
And hass.data['integrations'] is initialized before any integration is loaded.
The current suspicion is that you have some custom integration that is messing with that.

Can you try to remove constant_modifier and then restart to see if that helps?

from integration.

If it still is not working without that, can you post your logs from startup with debug enabled for custom_components.hacs?
