The test wraps agent_executor.invoke() with list(), but invoke() returns a dictionary, not an iterator. Using list() on a dict produces a list of keys (e.g., ['input', 'output']), which is not meaningful for this test. Unlike stream() which returns an iterator that should be consumed with list(), invoke() returns the result directly. While this doesn't cause the test to fail (the invoke still runs and span data is captured), it's misleading code that suggests the API works differently than it does.
