ACS Files update/create problem

Hello! We used next code to create files in cloud database:

ACS.Files.create({
        name: req.files.InputFileMedia.name,
        file: req.files.InputFileMedia.path
    }, function (e) {
        if (e.success) {
            console.log("Save file OK");
        }
       }
     );

is it problem in cloud service? Thank you!
