Is there a hack ?

• n8n version:
• Database (default: SQLite):
• n8n EXECUTIONS_PROCESS setting (default: own, main):

Hi @Guillaume_C

Are you seeing any errors?

Did you check the option in the node’s parameters?

Trying to help, but need a little more context

Thank you Ria.
It s an issue of behavior. When you use the AI agent or the openai block, it doesn’t answer the same thing.

Did you already see something like that ?
