Error in Playground Single Agent

Reproduce the error from the Playground Single Agent tap on the current main branch and inspect the frontend entry point that renders its response. Trace the object containing ai_model_id, metadata, content_type, role, name, items, encoding, finish_reason, and status to identify where it is rendered as a React child. Done means the Single Agent playground renders successfully without this error while the process and multi-agent paths remain working.

Using the current main branch and using the Playground Single Agent tap (process and multi agent without any issue):

Error: Objects are not valid as a React child (found: object with keys {ai_model_id, metadata, content_type, role, name, items, encoding, finish_reason, status}). If you meant to render a collection of children, use an array instead.
