Schemas, Pydantic, and validation — making the model return real data (step 6/9) · structured output

The model returned a response missing the required email field. In real code, Ticket.model_validate_json(raw) would raise ValidationError. Here, the assertion on line 8 raises KeyError before the assertion can run. Fix the script so it prints the string missing email instead of crashing.
