JavaScript: How to map two objects to get the output which map the Id of first object to the name of other object?

I am trying to make a function that maps the data2 object value to the name of the data1.

I tried to iterate data2 object2 with data1 but it is not working properly. I am able to map them but not getting the value of data1 when it is not there in data2.

Is there any way I can map properly to get the desired output mentioned in the code?

let data1 = {
    attributes: [{
            Id: 'test1',
            Name: 'Test1',
            Type: 'date'
        },
        {
            Id: 'test2',
            Name: 'Test2',
            Type: 'string'
        },
        {
            Id: 'test3',
            Name: 'Test3',
            Type: 'string'
        },
        {
            Id: 'test4',
            Name: 'Test4',
            Type: 'boolean'
        }
    ]
};

let data2 = {
    value: [{
            test1: '10-12-2021',
            test2: '4'
        },
        {
            test3: '3',
            test4: true
        },
        {
            test1: '12-12-2023',
            test3: '42'
        }
    ]
};

//output

let ouput = {
    rows: [{
            Test1: '10/12/2021',
            Test2: '4',
            Test3: '',
            Test4: ''
        },
        {
            Test1: '',
            Test2: '',
            Test3: '3',
            Test4: 'Y'
        },
        {
            Test1: '12/12/2023',
            Test2: '',
            Test3: '42',
            Test4: ''
        }
    ]
};

//function

function mapper(data1, data2) {
    let formattedValue = [];
    data2.value.forEach(val => {
        let data = {};
        for (let prop in val) {
            let name;
            const filter = data1.attributes.filter(el => el.Id === prop)[0];
            if (filter) {
                name = filter.Name;
                switch (filter.Type) {
                    case 'boolean':
                        data[name] =
                            val[prop] === true ? 'Y' : val[prop] === false ? 'N' : '';
                        break;
                    case 'date':
                        data[name] = new Date(val[prop]).toLocaleDateString();
                        break;
                    default:
                        data[name] = val[prop];
                        break;
                }
            }
        }
        formattedValue.push(data);
    });

    return formattedValue;
}

console.log(mapper(data1, data2));

same if I pass data2 as empty value I am looking to get below output

let data1 = {
  attributes: [
    {
      Id: 'test1',
      Name: 'Test1',
      Type: 'string'
    },
    {
      Id: 'test2',
      Name: 'Test2',
      Type: 'string'
    },
    {
      Id: 'test3',
      Name: 'Test3',
      Type: 'string'
    },
    {
      Id: 'test4',
      Name: 'Test4',
      Type: 'boolean'
    }
  ]
};

let data2 = {
  value: [
  ]
};

//output

let ouput = {
  rows: [
    {
      Test1: '',
      Test2: '',
      Test3: '',
      Test4: ''
    },
  ]
};
