Tell us what’s happening:

Can someone help me? i cant pass these two goals: 13: Calling validateManifest() with { destination: " " } should return the new object { containerId: “Missing”, destination: “Invalid”, weight: “Missing”, unit: “Missing”, hazmat: “Missing” } without mutating the source input. You can use String.trim() to remove whitespace from a string.
If the input manifest object is not valid, 15: your validateManifest function should return an object describing missing and/or invalid properties.

Your code so far

let cargo1 = {
  containerId: 101,        
  destination: "New York",  
  weight: 100,               
  unit: "lb",                
  hazmat: false,             
};

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

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

  return newManifest;
};

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

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

  
  if (!Object.hasOwn(manifest, "destination")) {
    errors.destination = "Missing";
  } else if (
    typeof manifest.destination !== "string" ||
    manifest.destination === "" 
  ) {
    errors.destination = "Invalid";
  }

  if (!Object.hasOwn(manifest, "weight")) {
    errors.weight = "Missing";
  } else if (
    typeof manifest.weight !== "number" ||
    Number.isNaN(manifest.weight) ||
    manifest.weight <= 0
  ) {
    errors.weight = "Invalid";
  }

  
  if (!Object.hasOwn(manifest, "unit")) {
    errors.unit = "Missing";
  } else if (manifest.unit !== "kg" && manifest.unit !== "lb") {
   
    errors.unit = "Invalid";
  }

  
  if (!Object.hasOwn(manifest, "hazmat")) {
    errors.hazmat = "Missing";
  } else if (typeof manifest.hazmat !== "boolean") {
    errors.hazmat = "Invalid";
  }

  
  return errors;
};
const processManifest = (manifest) => {
  const validationResult = validateManifest(manifest);

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



processManifest(cargo1)

what did you try to debug this?
For eg. Did you try running the function with the input and checking your output against the test? Was it the same or different?
Anything else you thought to try?

Hi @laker109 ,

What happens when you test with console.log(validateManifest( { destination: " " }))?

Does it match the expected result? What small change can you make to make sure it does?

Happy coding!
