I have a file stored in this.form.imagesFile variable. It contains file below:

And I want to send it using FormData and AJAX. FYI: I am using Vue and Laravel.

let getImg = [];
        this.form.variantsProd.forEach((item) => {
            let totalImagesFile = $('.images' + item.id)[0].files.length; //Total Images
            let imagesFile = $('.images' + item.id)[0];
            for (let i = 0; i < totalImagesFile; i++) {
                getImg.push(imagesFile.files[i]);
            }
            this.form.imagesFile = getImg;
        });
        this.form.totalImagesFile = getImg.length;

        let formData = new FormData();
        formData.append('imagesFile', this.form.imagesFile);

        $.ajaxSetup({
            headers: {
                'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content'),
            },
        });
        const token = localStorage.getItem('token-staff');
        var self = this;
        $.ajax({
            url: `${BASE_URL}/api/staff/products/store`,
            method: 'post',
            data: formData,
            enctype: 'multipart/form-data',
            cache: false,
            contentType: false,
            processData: false,
            dataType: 'JSON',
            async: true,
            headers: {
                'Content-Type': undefined,
            },
            xhr: function () {
                let myXhr = $.ajaxSettings.xhr();
                return myXhr;
            },
            beforeSend: function (xhr) {
                xhr.setRequestHeader('Authorization', `Bearer ${token}`);
            },
            error: function (response) {
                console.log(response);
            },
            success: function (result) {
                if (result.errors) {
                    console.log(result);
                } else {
                    //
                } //endif
            },
        });

But when I try to get the file in controller, I get [object File]. So, I do gettype($imagesFile) and the result is string. This is obviously unexpected result. I want store the file in server. How can I do that?

public function store(Request $request)
{
    $imagesFile = $this->request->get('imagesFile');

    return response()->json([
            'success' => true,
            'message' => $imagesFile,
        ]);
}
