Lodash _.isEquals method returns true even the comparing two objects are equal

I am trying to compare two objects with Lodash. One is getting as input and the other one is from db.Below is my method.

    console.log(`isDataChanged - fromDbData : ${JSON.stringify(fromDbData)}`);
    console.log(`isDataChanged - inputData : ${JSON.stringify(inputData)}`);

    if(_.isEqual(fromDbData, inputData)){
        console.log("isDataChanged - equal data found");
        return false;
    }else{
        console.log("isDataChanged - different data found");
        return true;
    }

};

the object is looks like below

{
...
"data": {
    "type": "Date",
    "name": "test",
    "tag": "sample",
    "category": null,
    "time": null,
    "caption": "the caption",
    "value": "none"
}
}

As the input parameter i’m sending the data property of both objects.
So when the values inside the data object for both I am expecting false. But it’s returning true.
Can someone please help me to understand what’s happening here?
Thanks!
