This is an internal n8n validation error that occurs when:
There are malformed data structures (e.g., empty or undefined keys).
Or when a misinterpreted expression generates an unexpected value such as null where an identifier is expected (e.g., node alias, variable name, connection parameter).
Clear execution data before saving:
Open the node’s pre-execution panel (the OpenAI node).
Click “Clear execution data” or disable the save output option for the node (Save Data → “Never” or similar).
Then try saving/activating the workflow again.
Avoid invalid keys in the OpenAI response: Make sure the OpenAI prompt doesn’t produce objects with keys like <>, empty keys, or null as the key.
Don’t use null as aliases or node names: Sometimes, n8n interprets parts of structures as aliases for nodes or variables. If any part contains “alias”: null, it can cause errors when interpreting the reference.
