Describe the problem/error/question
I created a functioning AI Agent workflow that works in the workflow chat, but gives me an error using the n8n Workflow Chat. I updated the nodes and confirmed their version.
The odd extra is that the software, self-hosted on hostinger, says I am a version behind but I’m at the latest version.
What is the error message (if any)? Failed to send message
Agent node version is too old to support streaming responses. Please update the node.
Please share your workflow
