Screen.Recording.2025-01-02.at.13.53.04.mov

Source:

type Person record {
    string id;
    string firstName;
    string lastName;
    int age;
    string country;
    string courseName;
};

type Course record {
    string id;
    string name;
    int credits;
};

type Student record {
    string id;
    string fullName;
    string age;
    record {
        string title;
        int credits;
    } course;
    int totalCredits;
    string visaType;
};

function tnf(Person person, Course course) returns Student => {
    course: extracted1(person)
};

function extracted1(Person person) returns record { string title;  int credits; } {
    return {};
}

as captured in the above Data Mapping scenario, the generated function has picked an incorrect input type. In this case the generated function should be

function extracted1(Person person) returns record { string title;  int credits; } {
    return {
        credits: 0,
        title: ""
    };
}

and the mapping should be,

function tnf(Person person, Course course) returns Student => {
    course: extracted1(person.courseName)
};
