Instructor: As you can see here, we don't have age and gender in our user object. It is not throwing any errors because both of the fields are optional in our type.
With the help of required, we can make all our option fields to be required. Now, if I put required here in our user type, it would make the age and gender to be required also. It will throw the error that age and gender are required.
Now, if I put the age here and gender here, the error will go away.
