Google Assistant integration throwing 404 errors when an entity changes state

Hey guys!
I hope you are all doing super well!

I’ve been receiving, since months now, these error messages from Google everytime that an entity changes state: Request for failed: 404

Wanting to remove them, I’ve read a bit and decided to re-create my google-assistant setup.
New project on the google project console and new settings in my configuration.yaml.

Unfortunately, the problem remains!
I’ve read that this had to do with HA sending states for non-sync devices.

I can guarantee that after asking google, successfully, to sync my devices much time, the issue continues.

I also enabled debug logs for this component, and this what I get.

2020-09-01 16:05:30 ERROR (MainThread) [homeassistant.components.google_assistant.http] Request for failed: 404
2020-09-01 16:05:30 DEBUG (MainThread) [homeassistant.components.google_assistant.http] Response on with data {'requestId': '8a67728a1c984a5983d7b102b04d4c7a', 'agentUserId': '91ab72c47ad346178909cb28f1c4c345', 'payload': {'devices': {'states': {'switch.lavalamp_bedroom': {'online': True, 'on': True}}}}} was {
  "error": {
    "code": 404,
    "message": "Requested entity was not found.",
    "status": "NOT_FOUND"

Be reassured that those entities exist in Google home, I can toggle them from there with no issue.

My question is, did anyone ever encountred this? And if yes, how can I solve it?

P.s Nabu Casa is NOT an option. I went to HA to keep everything that I could local and using their cloud would go against that

Then why on earth are you using Google Assistant?

Cause google minis are 10$ a pop and can recognize my accent when using them.

If there was a local viable alternative, i’d use it.

It sounded like you were concerned about privacy by wanting to keep everything local. Nabu Casa is far less of a privacy concern than Google Assistant.

I’m not sure why you marked my post as the solution. I really haven’t offered one. I was just interested in your reasoning.

My apologies for the solution, it was a misclick.

As for the privacy concerns, unfortunately, the 12 Minis are too useful to be removed.

I will replace with something local once it exists.

Ok, if you are going to use them Nabu Casa is the least of your worries and will probably sort out your issues. Otherwise there’s this:

Not sure how good it is.

Almond is not a viable replacement solution. By far.

As for Nabu Casa, I’d rather control my connection.
