Parse 122 error upload

If I save text without having any text in the field I get this error message in Parse.com: Update Failure - The operation couldn't be completed(Parse error 122.) If I press OK and then try to dismiss the view with Cancel(a button item) the app crashes. Any ideas? I think a valid file name at Parse.com has to contain at least 1 character. But how do I do something to stop the user from saving then?

This my code:

    - (IBAction)save:(id)sender {

        // Create PFObject with profile information
        PFUser *profile = [PFUser currentUser];
        [profile setObject:nameTextField.text forKey:@"name"];
        [profile setObject:titleTextField.text forKey:@"title"];
        [profile setObject:locationTextField.text forKey:@"location"];

        // Profile image
        NSData *imageData = UIImageJPEGRepresentation(profileImageView.image, 0.8);





        NSString *filename = [NSString stringWithFormat:@"%@", nameTextField.text];




        PFFile *imageFile = [PFFile fileWithName:filename data:imageData];
        [profile setObject:imageFile forKey:@"profileimageFile"];





        // Show progress
        MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
        hud.mode = MBProgressHUDModeIndeterminate;
        hud.labelText = @"Updating";
        [hud show:YES];

        // Upload profile to Parse


        if(nameTextField.text.length==0 && titleTextField.text.length==0 && locationTextField.text.length==0)





              [hud hide:YES];



        [profile saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {

                if (error) {



                    [[[UIAlertView alloc] initWithTitle:@"Profile Information" message:@"Fill in atleast one field" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil]show];


                    [hud hide:YES];


                }
                else {



                // Show success message
                UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"" message:@"Successfully updated profile" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
                [alert show];


                [hud hide:YES];

                [self dismissViewControllerAnimated:YES completion:nil];

                [self performSegueWithIdentifier:@"profile" sender:self];



            }

        }];

    }


    - (IBAction)Cancel:(id)sender {

        [self dismissViewControllerAnimated:YES completion:nil];
        [self performSegueWithIdentifier:@"profile" sender:self];
    }
