Tell us what’s happening:

Code perfectly correct, validation not working prorperly.
I removed the console.log line, added the function correctly returning null and still the validation isn’t working. Why?

Your code so far

const rawData = {
  "Computer Science": {
    Dept_code: "CSE",
    programs: [
      {
        id: "CSE101",
        name: "Database Management System",

        instructors: [
          { id: "INS001", name: "Alejandro", email: "alejandro@example.com", officeHours: "Sun-Tue 10AM-12PM" },
          { id: "INS002", name: "Kenji", officeHours: null },
        ],
      },

Welcome to the forum @Djuseppe,

It looks like you may have changed the starting code in areas you were not asked to change, which will cause the tests to fail. Please click the reset button to restore the original code and try again.

The starting code included this, which you removed:

const normalizedData = normalizeDirectory(rawData);
