Greetings all,
I’m running HAOS 2026.3.4. When i perform an upgrade to 2026.4.1, my ha core check command throws this error: KeyError: ‘triggers’.
I’ve grepped through al the files but can’t find a reference to it.
I’ve tried saving my automations through the UI again, hoping it will auto correct. No succes.
Can someone help me to perform the upgrade again, but without errors?
Many thanks in advance.
Pre-upgrade: the command “ha core check” runs perfectly fine.
Post-upgrade: This error.
I’m getting the same error today.
Might want to post this here or add an issue: 2026.4: Infrared never left the chat
Post the error from the log please, not your abridged version.
Pre update:
[core-ssh ~]$ ha core check

It looks like you have been editing your automation file manually and failed
to expand on @Hellis81’s comment, your 2nd automation isn’t properly formatted for UI use, it’s formatted for yaml use. The automation itself looks fine but it should have been updated to the new keys, which would have been automatic if you saved the automation from the UI.
You can likely rectify this by just changing trigger: to triggers: in your 2nd automation.
Regardless, there does seem to be a bug somewhere because the legacy keys should still work or should be translated to the new keys under the hood.
I’ve re-saved all the automations in the UI. Same error persists.
I’m not as knowledgeable as Petro. But something tells me the issue is at the line before triggers:.
If you have access to the automations.yaml file then open it and search for triggers: and check the line above which should be the end of the previous automation.
What I expect you will find is in some automation the actions: has been deleted which means you will see a pattern like this:
triggers:
...
...
conditions:
..
actions:
...
...
triggers:
...
...
conditions:
..
triggers: # note here the missing action above.
...
...
conditions:
..
actions:
...
Did you change the fields I suggested?
I’ll try this right now.

Right, the error though is showing code where it implicitly tries to get triggers from a dictionary. The key does not exist, so an exception is created.
So, what do I need to do, to resolve this exception?
And why does it come since 2026.4?
Is it possible the issue is in the custom made blueprint?
I’ve deleted all automations one by one, after the last one, the issue was gone.
However when I recreate the motion automations, the error comes back.
I don’t have a clue where to look.

Yes, it’s possible. If that’s the case, write up an issue attaching that blueprint. Blueprint keys should be translated from legacy keys (trigger, platform, etc) to the modern keys.
I’ve deleted all automations again, deleted the blueprint as well. ha core check, succesfull.
After that I’ve created a simple automation through the GUI:
[core-ssh config]$ ha core restart && ha core check
Processing... Done.
Command completed successfully.
Processing... Done.

Can anyone guide me to the right direction? 
I’ve created a new VM in Proxmox and I’ve completed a brand new HA OS Install 2026.4.1.
I did not restore a back-up, I’ve created a new automation. Same error.
P.S. I’ve made the automation only through the web interface, no YAML from my side
