fix: prevent crash when version is missing in data using optional chaining

I believe the 'version' field should be optional because, according to the source code in the OutputData interface (as seen here), the 'version' property is not marked as required. This suggests that there may be cases where the 'version' field is absent, and the code should handle such cases gracefully.

This is my first contribution, so if I've missed anything or need to address any other points, I would really appreciate your guidance. Thank you for your time!
