Inappropriate Error Handling When Adding Images Without a Barcode

[N3jm4n]

What

When attempting to add an image without a barcode, the system does not properly handle the scenario. Instead of displaying a user-friendly error message about the missing barcode, the following issues occur:

• A message stating "Upload error" is displayed.
• The browser console logs an error:
  POST https://world.openfoodfacts.org/cgi/product.pl 500 (Internal Server Error).

Steps to reproduce the behavior

1. Go to https://world.openfoodfacts.org/cgi/product.pl?type=search_or_add&action=display.
2. Attempt to add a product image that does not contain a barcode.
3. Observe the error messages displayed on the interface and in the console.

Expected behavior

• The system should display a clear, user-friendly message indicating that the uploaded image does not contain a barcode.
• The system should not throw a 500 Internal Server Error or any other unexpected error.
