Tell us what’s happening:

This code fails test 15 even though the output displays everything correctly. Can you tell me why this code fails test 15? What should I fix to make the code pass test 15?

Your code so far

function normalizeUnits (manifest) {
  const newManifest = {...manifest};

  if (newManifest.unit.toLowerCase() === "lb") {
    newManifest.weight = Number((newManifest.weight * 0.45).toFixed(2));

  }

  return newManifest;
}

function validateManifest (manifest) {
  const errors = {};

  if (manifest.containerId === undefined) {
    errors.containerId = "Missing";
  } else if (typeof manifest.containerId !== "number" || !Number.isInteger(manifest.containerId) || manifest.containerId <= 0) {
    errors.containerId = "Invalid";
  }

Welcome to the forum @lkhoa8606,

Does it make sense to manipulate this value before you test its validity?

Happy coding
