Hey n8n community! I’ve searched the forum but couldn’t find a solution, so I’m posting here for help.
The “AI Agent” node isn’t passing the chatInput value to the prompt, even though it’s present in the “Merge” node’s output. This causes the “Simple Memory” node to fail as well.
The error
“AI Agent” Prompt (User Message) shows: no message provided (indicating chatInput is undefined).
“Simple Memory” error: Error in sub-node ‘Simple Memory’ (because it relies on “AI Agent” output).
The output
The “Edit Fields” node (last node) doesn’t produce output because “Simple Memory” fails due to the “AI Agent” not passing data correctly.
Expected Output:
{
“text”: “AI response”,
“sessionId”: “session-1743115817206”
}
