Multiple reportStateAndNotification requests with different 'agentUserId' which fails

Configuration
1

I recently configured google assistant integration following these steps.
Everything seems to be working just fine but I see a lot of:

[homeassistant.components.google_assistant.http] Request for https://homegraph.googleapis.com/v1/devices:reportStateAndNotification failed: 404

Errors in the log. I enabled debug prints and it looks like this:

(I replaced the real values, X Y and Z are constant and do not change)
Seems like HomeAssistant is trying to request reportStateAndNotification with 3 different 'agentUserId’s: X, Y and Z, and it appears that only Z succeeds.
This happens every 2 minutes or so, in each time the 3 agentUserId’s are the same X, Y and Z.
Anyone has any ideas?

Update: Apprently Z is my user_id in homeasissnant, I can’t find any other users that match X and Y, but I remember I had to reset my password once by deleting my current user and adding a new one, could this be related? if so, how can I clean it up?
