Hey @LilDaniel0,

hey @LilDaniel0 what version of n8n were you on before the upgrade?

@LilDaniel0 , the Structured Output Parser expects the stringified JSON of the following format:

{"output":{"next_agent":"B1"}}

Note the expected JSON-schema conformant object should be passed as a property output of a wrapper object. This normally is being handled automatically. In your case the agent fails to format the JSON in the required form. You can try to fix this by changing your prompt or try more powerful model.
