The new code calls `self.graphql_span.__exit__(None, None, None)` unconditionally, which tells the span that no exception occurred. In the `Span.__exit__` method (tracing.py:399-400), exceptions are detected via the `value` parameter and result in setting the span status to `INTERNAL_ERROR`. By always passing `None`, exceptions raised during GraphQL operations will not be reflected in the span's status, losing important error context for observability.
