The code calls `_graphql_span.__exit__(None, None, None)` unconditionally in the finally block, which prevents exceptions from being recorded on the span. The `Span.__exit__` method checks `if value is not None` to set `SPANSTATUS.INTERNAL_ERROR`, but since `None` is always passed for the exception value, any exceptions raised during GraphQL execution will result in spans without proper error status. This should use `sys.exc_info()` to pass actual exception information.
