ValueError: tool_choice and tool_config.tool_choice must match

[kumardevendra]

Not able to set tool_choice to "required"

Below is my code...

self.agent_config = AgentConfig(
            model=MODEL_NAME,
            instructions=WEB_SEARCH_INSTRUNCTION_PROMPT,
            sampling_params={
                "strategy": {
                    "type": "greedy",
                },
            },
            toolgroups=["builtin::websearch"],
            tool_choice="required", # This is throwing error when changed to required from auto.
            input_shields=[],
            output_shields=[],
            enable_session_persistence=False,
        )

Error Logs ....
