Build a Cargo Manifest Validator, Test 21, 25, and 26

My code is failing tests 21, 25, and 26 on the Cargo Manifest challenge. I’ve implemented both validateManifest and processManifest with the required console.log calls, but I think I am missing an edge case or a formatting requirement. Need help checking why these specific tests aren’t passing.

const cargo = {
  containerId: 1,
  destination: "AU",
  weight: 400,
  unit: "lb",
  hazmat: true
}
const normalizeUnits = (manifest) => {
  const cargo = { ...manifest }
  if (cargo.unit === "kg") {
    return cargo
  } else if (cargo.unit === "lb") {
    cargo.weight = Number.parseFloat(cargo.weight * (0.45));
    cargo.unit = "kg";
  }
  return { ...cargo }
}

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

  // Safety guard: Ensure manifest is a valid object before inspecting properties
  if (!manifest || typeof manifest !== "object" || Array.isArray(manifest)) {
    return {
      containerId: "Missing",
      destination: "Missing",
      weight: "Missing",
      unit: "Missing",
      hazmat: "Missing"
    };
  }

  // 1. containerId (Must be a positive integer > 0)
  if (!Object.hasOwn(manifest, "containerId")) {
    cargo.containerId = "Missing";
  } else if (!Number.isInteger(manifest.containerId) || manifest.containerId <= 0) {
    cargo.containerId = "Invalid";
  }

  // 2. destination (Must be a non-empty string)
  if (!Object.hasOwn(manifest, "destination")) {
    cargo.destination = "Missing";
  } else if (typeof manifest.destination !== "string" || manifest.destination.trim() === "") {
    cargo.destination = "Invalid";
  }

  // 3. weight (Must be a positive finite number > 0)
  if (!Object.hasOwn(manifest, "weight")) {
    cargo.weight = "Missing";
  } else if (typeof manifest.weight !== "number" || !Number.isFinite(manifest.weight) || manifest.weight <= 0) {
    cargo.weight = "Invalid";
  }

  // 4. unit (Must be exactly "lb" or "kg")
  if (!Object.hasOwn(manifest, "unit")) {
    cargo.unit = "Missing";
  } else if (manifest.unit !== "lb" && manifest.unit !== "kg") {
    cargo.unit = "Invalid";
  }

  // 5. hazmat (Must be a boolean)
  if (!Object.hasOwn(manifest, "hazmat")) {
    cargo.hazmat = "Missing";
  } else if (typeof manifest.hazmat !== "boolean") {
    cargo.hazmat = "Invalid";
  }

  // Return empty object if all checks pass, otherwise return the error object
  return cargo;
};
console.log(typeof NaN);
console.log(validateManifest({ containerId: 1, destination: "Santa Cruz", weight: 304, unit: "kg", hazmat: false }));

const processManifest = (manifest) => {
  const valid = validateManifest(manifest);
  
  // Case 1: Valid manifest (error object has 0 keys)
  if (Object.keys(valid).length === 0) {
    const norm = normalizeUnits(manifest);
    console.log(`Validation success: ${norm.containerId}`);
    console.log(`Total weight: ${norm.weight} kg`);
  } else {
    // Case 2: Invalid manifest
    console.log(`Validation error: ${manifest.containerId}`);
    console.log(validateManifest(manifest));
  }
};

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