@MikeRyanDev Thanks Mike! I appreciate you proactively fixing the integration on our side :) Can you have a look at the failing coverage please? |

Thanks @DouweM! I've added an additional test to increase coverage. I'm seeing spurious errors like: RuntimeError: Failed starting Temporal dev server: HTTP status server error (500 Internal Server Error) for url (https://temporal.download/cli/default?arch=amd64&platform=linux&format=tar.gz&sdk-name=sdk-python&sdk-version=1.19.0)Maybe Temporal is sleepy this morning. I'll give it a few hours and re-run the build in a bit. |

Hi there! I'm a developer on the AG-UI/CopilotKit team. We are changing the behavior of shared agent state in an upcoming release of CopilotKit, where the agent state object will always be supplied when running an agent. If state hasn't been configured, it will default to an empty object.
This change in behavior causes Pydantic AI to throw a
UserError, since its current implementation requires aStateHandlerto be configured if any state value is present.This PR changes Pydantic AI's AG-UI implementation to silently accept an empty object as the state value, even if a
StateHandlerisn't present.
