Axios returning parsed JSON data in ReactJS with an undefined value for file key

Question

I am having an odd issue where my Laravel API is returning JSON data to my react front-end via Axios and then Axios is parsing the data and returning an undefined value for a specific key "file".

Ive added a transformResponse function to the Axios get method that logs the response before and after doing my own parsing and I still get the same result. Im also using the reviver parameter to log the value when the key is file.

api.get(`xxxxx`, {
            transformResponse: (res) => {
                console.log(res);

                const  data = JSON.parse(res, (key,value) => {
                    if (key === 'file' && value !== null) console.log(value);
        
                    return value;
                });

                console.log(data);

                return data;
            },
        }).then(res => {

The output of the first log:

{"data":{"value":{"value": 20,"users": [],"file":{"id":20,"fileable_id":2,"folder_id":21,"group_id":null,"name":"IMG_6274.jpg","size":4263000,"downloads":1,"created_at":"2023-11-01T17:24:17.000000Z","updated_at":"2023-11-01T17:24:29.000000Z","deleted_at":null,"extension":"jpg","size_formatted":"4.07 MB","full_url":"https:\/\/ca-dev-stor.s3.us-east-2.amazonaws.com\/club\/2\/fields\/38\/2b837cdd-ee95-49a9-992d-74211b4400da.jpg"}}}}

The output of the second log:

{
    "id": 20,
    "fileable_id": 2,
    "folder_id": 21,
    "group_id": null,
    "name": "IMG_6274.jpg",
    "size": 4263000,
    "downloads": 1,
    "created_at": "2023-11-01T17:24:17.000000Z",
    "updated_at": "2023-11-01T17:24:29.000000Z",
    "deleted_at": null,
    "extension": "jpg",
    "size_formatted": "4.07 MB",
    "full_url": "https://ca-dev-stor.s3.us-east-2.amazonaws.com/club/2/fields/38/2b837cdd-ee95-49a9-992d-74211b4400da.jpg"
}

And the output of the third log:

{
    "data": {
        "value": {
            "value": 20,
            "users": [],
            "file": undefined
        }
    }
}

However if i take the original line and parse it as a string instead of from the response object i get no issue. Not sure how to fully reproduce this - mostly hoping someone has run into this issue before. Thanks!
