how to filter a complex object in react

Question

I have an object like the following.

example:[
{
    "Id":"100",
    "value":"Egor1",
    "children":{
        "pilot":[
            {
                "Properties":{
                    "Id":123,
                    "History":[
                        20191101,
                        20191112,
                        20191103
                    ]
                }
            }
        ]
    }
},
{
    "Id":"200",
    "value":"Egor2",
    "children":{
        "pilot":[
            {
                "Properties":{
                    "Id":234,
                    "History":[
                        20191001,
                        20191012,
                        20191003,
                        20190902
                    ]
                }
            }
        ]
    }
},
{
    "Id":"300",
    "value":"Egor3",
    "children":{
        "pilot":[
            {
                "Properties":{
                    "Id":456,
                    "History":[
                        20190901,
                        20190912,
                        20190903,
                        20191101
                    ]
                }
            }
        ]
    }
}

]

I have an input 20191101. Sometimes input can be 20191101,20191001. I need to filter the example if

children.pilot.properties.history[0]=== 20191101.

I tried the following:

const result = example.filter( task => task.children.pilot.properties.history.includes(getPbfValueByFilter(task.childen, input))
  );

getPbfValueByFilter method :

const getPbfValueByFilter = (allChilden, input) => {
const { features } = allChilden.pilot;
const test = input.toString().split(',');

if (isUndefined(features) || isEmpty(features)
|| isUndefined(features.properties.History)) {
return [];
}
 test.map((each) => {
 if (each === features.properties.History[0]) {
 console.log("here" + features.properties.History[0])
 return allChilden;
}

});
};

expected output :

[
{
    "Id": "100",
    "value": "Egor1",
    "children": {
        "pilot": [
            {
                "Properties": {
                    "Id": 123,
                    "History": [
                        20191101,
                        20191112,
                        20191103
                    ]
                }
            }
        ]
    }
}
]

I am getting the console part. But it is unable to fetch the result. I assume that 'includes' is not working as expected. What went wrong. Please advice. TIA.

According to the example object pilot is an array so the filter should be something like this:

const result = example.filter((task) =>
  task.children.pilot[0].properties.history.includes(
    getPbfValueByFilter(task.children, input)
  )
);
