Since updating n8n yesterday, all of my existing workflows—and even new ones—using AI Agent nodes got affected. As shown in the image below, the connectors are missing entirely.
Is anyone else running into this issue? Any ideas on how to fix it? Really appreciate the help! 
docker.n8n.io/n8nio/n8n:stable)own (default)My guess would be that there was a breaking change somewhere along the way and now you would have to manually replace these nodes with the new version of the Ai Agent node (which doesn’t look like this one).
Alternatively you could roll back if you wish, but I don’t know if the connections will be restored..
I believe it’s a frontend problem - the active workflows still seem to be running properly
Yes, it’s possible the change affects the UI, which is actually good, as it doesn’t break the logic. Still, you will most probably have to go down the manual route if you need to make changes to the workflows. Good news would be it can be on-demand, not all at once 
Hello, did you manage to solve the problem without downgrading n8n ?
problem came from the nginx configuration if you are working on a ubuntu VM
Update: Was able to fix the problem! It had to do with our CSP header in our Caddy config.
