Metric-Imperial Converter expected value error

JavaScript

So my code passes both the unit and functional tests but when i run it for the project tests themselves the following test fail:

  • You can convert 'gal' to 'L' and vice versa. (1 gal to 3.78541 L)
  • You can convert 'lbs' to 'kg' and vice versa. (1 lbs to 0.453592 kg)
  • You can convert 'mi' to 'km' and vice versa. (1 mi to 1.60934 km)

I found the fix is to fix it to 5 decimal points but no matter what I do it doesn’t work for the response, only for the string part. Here’s the related snippet of my code:

convertHandler.js:

// Function to generate the output string
  this.getString = function(initNum, initUnit, returnNum, returnUnit) {
    const spellOutInitUnit = this.spellOutUnit(initUnit);
    const spellOutReturnUnit = this.spellOutUnit(returnUnit);
    let result = `${initNum} ${spellOutInitUnit} converts to ${parseFloat(returnNum.toFixed(5))} ${spellOutReturnUnit}`;
    return result;
  };

api.js:

// Define the route for conversion
  app.get('/api/convert', (req, res) => {
    let input = req.query.input;
    
    // Extract the number and unit from the input
    let initNum = convertHandler.getNum(input);
    let initUnit = convertHandler.getUnit(input);
    
    // Validate the unit
    const validUnits = ['gal', 'l', 'lbs', 'kg', 'mi', 'km'];
    if (!validUnits.includes(initUnit)) {
      return res.json({ error: 'invalid unit' });
    }
    
    // Validate the number
    if (isNaN(initNum)) {
      return res.json({ error: 'invalid number' });
    }
    
    // Get the return unit and convert the number
    let returnUnit = convertHandler.getReturnUnit(initUnit);
    let returnNum = convertHandler.convert(initNum, initUnit);
    
    // Generate the output string
    let string = convertHandler.getString(initNum, initUnit, returnNum, returnUnit);

    // Send the response
    res.json({
      initNum: initNum,
      initUnit: initUnit,
      returnNum: parseFloat(returnNum.toFixed(5)),
      returnUnit: returnUnit,
      string: string
    });
  });

basically when I input “1lbs” the string is “1 pounds converts to 0.45359 kilograms” which is great but then the response under it is {“initNum”:1,“initUnit”:“lbs”,“returnNum”:0.453592,“returnUnit”:“kg”,“string”:“1 pounds converts to 0.45359 kilograms”} where returnNum is the full decimal value.
