Prevent File Upload when error occurs in the validation

Is there a way to stop file upload in multer when validation fails during saving into a MongoDB database?
My code goes like this.
```
const EmployeeSchema = new mongoose.Schema(
{
EmployeeId: {
type: String,
required: true,
unique: true,
}
firstName: String,
lastName: String,
imagePic: String,

}

const PUBLIC_DIR = "./public/";

// set multer disk storage
const storage = multer.diskStorage({
destination: (req, file, cb) => {
cb(null, PUBLIC_DIR );
},
filename: (req, file, cb) => {
//generate random uuid
const fileName = uuidv4() + path.extname(file.originalname);
cb(null, fileName);
},
});

const upload = multer({
storage: storage,
fileFilter: (req, file, cb) => {
if (
file.mimetype == "image/png" ||
file.mimetype == "image/jpg" ||
file.mimetype == "image/jpeg"
) {
cb(null, true);
} else {
cb(null, false);
return cb(new Error("Only .png, .jpg and .jpeg format is allowed!"));
}
},
});

// Create Employee
router.post("/", upload.single("file"), async (req, res) => {
const newEmployee = new Employee(req.body);
try {
// save the generated filename in our MongoDB Atlas database
newEmployee.imagePic = req.file.path;

const savedEmployee = await newEmployee.save();
res.status(200).json(savedEmployee);
} catch (error) {
res.status(500).json({ error: error });
}
});
```
I noticed that if validation or an error is thrown during the save() then the file is still uploaded in my upload directory.
