Tell us what’s happening:

Hi there!
I’m having trouble with test 15 and I don’t know what I’m doing wrong.
Can anyone please give me a hint

Your code so far

function normalizeUnits(manifest) {
  let copy = {...manifest}
  if (copy.unit === "lb") {
    copy.weight *= .45;
    copy.unit = "kg"
    return copy;
  }
  return copy;
}

function validateManifest(manifest) {
  let copy = {};
  
  if(!(Object.hasOwn(manifest, "containerId"))){
    copy.containerId = "Missing";
  } else if(typeof manifest.containerId !== 'number' || manifest.containerId <= 0 || manifest.containerId % 1 !== 0) {
    copy.containerId = "Invalid";
  };
  if(!(Object.hasOwn(manifest, "destination"))){
    copy.destination = "Missing";
  } else if(typeof manifest.destination !== 'string' || manifest.destination.trim() == "") {
    copy.destination = "Invalid";
  };
  if(!(Object.hasOwn(manifest, "weight"))){
    copy.weight = "Missing";
  } else if(typeof manifest.weight !== 'number' || manifest.weight <= 0 || manifest.weight % 1 !== 0) {
    copy.weight = "Invalid";
  };
  if(!(Object.hasOwn(manifest, "unit"))){
    copy.unit = "Missing";
  } else if(manifest.unit != 'lb' && manifest.unit != "kg") {
    copy.unit = "Invalid";
  };
  if(!(Object.hasOwn(manifest, "hazmat"))){
    copy.hazmat = "Missing";
  } else if(manifest.hazmat != true && manifest.hazmat != false) {
    copy.hazmat = "Invalid";
  };

  return copy;
}

function processManifest(manifest) {
  const normalizedWeight = normalizeUnits(manifest);
  const validatedManifest = validateManifest(manifest);
  if(Object.keys(validatedManifest).length === 0) {
    console.log(`Validation success: ${manifest.containerId}`);
    console.log(`Total weight: ${normalizedWeight.weight} kg`)
  } else {
    console.log(`Validation error: ${manifest.containerId}`);
    console.log(validatedManifest);
  }
}

console.log(processManifest({ containerId: -88, destination: "Soledad", weight: NaN }));

Hi @jemmelfloranza,

What do you see in the console when you call the function like this?

processManifest({ containerId: -88, destination: "Soledad", weight: NaN, unit: "pound", hazmat: "1" });

Happy coding!

Oh I see now where my error is, I’m not using the right type validation. Thank you very much!
