Build a Cargo Manifest Validator - Build a Cargo Manifest Validator

Tell us what’s happening:

I am on the Build a Cargo Manifest Validator. My tests are matching the results in the Instructions, but I keep getting the error ,“If the input manifest object is valid, your processManifest function should log a success message with the object’s containerId, and then log the object’s weight in kilograms. You should use normalizeUnits() for the conversion and have two console.log() calls.” I have tried several different ways getting the correct output, but still not passing.

Your code so far

const normalizeUnits = (manifest) => {
  const normalManifest = { ...manifest};
  if (normalManifest.unit === "lb") {
    normalManifest.weight *= 0.45;
    normalManifest.unit = "kg";    
  } 
  return normalManifest;
};

const validateManifest = (manifest) => {
  const validManifest = { ...manifest};

  if (!Object.hasOwn(validManifest, "containerId")) {
    validManifest.containerId = "Missing";
  } else if (!Number.isInteger(validManifest.containerId) || 
              validManifest.containerId <= 0) {
                validManifest.containerId = "Invalid";
  } else {
    delete validManifest.containerId;
  }

  if (!Object.hasOwn(validManifest, "destination")) {
    validManifest.destination = "Missing";
  } else if (String(validManifest.destination).trim() === "" || typeof(validManifest.destination) != "string" ) {
    validManifest.destination = "Invalid";
  } else {
    delete validManifest.destination;
  }

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

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


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

    return validManifest;
};

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


processManifest({ containerId: 55, destination: "Carmel", weight: 400, unit: "lb", hazmat: false });
processManifest({ containerId: -88, destination: "Soledad", weight: NaN }); 
processManifest({ destination: "Watsonville", hazmat: true });

Welcome to the forum @nicholas.schock,

The tests reassign the functions, so either declare your arrow functions with let or convert them to regular functions.

Staff is working on getting a note up about that.

Happy coding

Thank you. I felt like I was going insane.

:rofl: I did too the first time I tried to troubleshoot someone’s code for this challenge with arrow functions like yours.
