FileName cannot be empty

[bastoune]

Hi,

When I upload some csv file, I get the error SplFileObject::__construct():Filename cannot be empty in Lexer.php line 50.
when I echo $file->getClientOriginalName(), it give me the right name which is just "liste.csv".
In the headers sended, I do have
Content-Disposition: form-data; name="file"; filename="liste.csv"
Content-Type: application/vnd.ms-excel

here is my code

    $file = Input::file('file');
                //echo $file->getClientOriginalName();
    $config = new LexerConfig();
    $config
                    ->setDelimiter(";")
                    ->setToCharset('UTF-8')
    ;
    $lexer = new Lexer($config);
    $interpreter = new Interpreter();

    $salarie_csv = [];
    $errors = [];
    $lineNb = 0;
    $interpreter->addObserver(function (array $rows) use (&$salarie_csv, &$lineNb, &$errors) {
        //some code
    });
    $lexer->parse($file, $interpreter);

    return Response::json($errors, 200);

When I limit the number of line to 20.000 it works well, the file is initially 2.5Mb size.
Is there a row number limit/ file size limit ?
