• There is a mismatch between the asserted message type and the error message text. The assertion checks for 'game_state' but the error message expects 'problem'. Please align the expected type and error message for consistency.

assert msg.get("type") == "game_state", (f"Expected type 'problem', got {msg.get('type', 'None')}")

• Ensure that 'submission_result' is always defined before merging it with 'result'. If there is a risk that operator.process_submission may not return a valid dictionary, add a fallback or a check to avoid a runtime error.

await player.send_event({"type": "submission_result", "data": {**result, **submission_result}})
