SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data Error On laravel 5

When I try to upload a image on Laravel 5 , I am getting this error:

SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data.

And Here is My JSON Values:

Array
(
    [file_id] => 0
    [product_id] => 8
    [images] => Array
        (
            [0] => Symfony\Component\HttpFoundation\File\UploadedFile Object
                (
                    [test:Symfony\Component\HttpFoundation\File\UploadedFile:private] => 
                    [originalName:Symfony\Component\HttpFoundation\File\UploadedFile:private] => Screenshot from 2015-10-19 150133.png
                    [mimeType:Symfony\Component\HttpFoundation\File\UploadedFile:private] => image/png
                    [size:Symfony\Component\HttpFoundation\File\UploadedFile:private] => 19066
                    [error:Symfony\Component\HttpFoundation\File\UploadedFile:private] => 0
                    [pathName:SplFileInfo:private] => /tmp/phpnbNIJk
                    [fileName:SplFileInfo:private] => phpnbNIJk
                )
        )
)

How Can I Solve This?
