• The operation should be 'update' not 'delete'. This is a copy-paste error that will result in misleading error messages when update operations fail.

• The operation parameter is set to 'delete' but this is an update operation. It should be 'update' to accurately reflect the operation that failed. This is also noted in the documentation at docs/user-stories/product/edit_product.md line 22.

• The operation parameter should be 'update' not 'delete'. This error occurs in the update use case but incorrectly reports the operation as 'delete', which would be misleading for debugging.
