The _wrap_synchronous_message_iterator generator function lacks a try...finally block around the iteration loop. If an exception occurs during iteration, or if the consumer breaks out of the loop early, _set_output_data(..., finish_span=True) will never be called and the span will never be closed via __exit__(). This results in unclosed spans and potential resource leaks. Other integrations like langchain.py use try...finally to ensure proper span cleanup.

The _wrap_synchronous_message_iterator function lacks try/finally handling around the iteration loop. If an exception is raised during iteration, or if the consumer breaks out of the loop early (e.g., for event in stream: break), or if the generator is explicitly closed, the code after the for loop (lines 371-389) will never execute. This leaves the span unclosed, causing resource leaks and incomplete traces. Other integrations like google_genai and openai_agents use try/finally patterns to ensure span cleanup.
