Description

Uploading the same media file two times in the Upload Media dialog of the Content Editor might result in an empty client-side error and the following error in the log records:

Exception: Sitecore.Exceptions.DuplicateItemNameException
Message: The item name "your_image" is already defined on this level.
Source: Sitecore.Kernel
at Sitecore.Data.Items.ItemUtil.AssertDuplicateItemName(Item destinationItem, Item sourceItem, String name)
at Sitecore.Data.Items.ItemUtil.AssertItemName(Item destinationItem, Item sourceItem, String name)
at Sitecore.Data.Items.Item.Add(String name, TemplateID templateID)
at Sitecore.Resources.Media.MediaCreator.CreateItem(String itemPath, String filePath, MediaCreatorOptions options)
at Sitecore.Resources.Media.MediaCreator.AttachStreamToMediaItem(Stream stream, String itemPath, String fileName, MediaCreatorOptions options)

at Sitecore.Resources.Media.MediaUploader.UploadToDatabase(List`1 list)
at Sitecore.Resources.Media.MediaUploader.Upload()
at Sitecore.Pipelines.Upload.Save.Process(UploadArgs args)

The issue appears when uploading a file with the name which already exists in the same folder and it does not happen with admin user.

 

Solution

Consider the following solutions:

• To allow uploading a media file with the same name, you can set the AllowDuplicateItemNamesOnSameLevel setting value to true. Note that the setting must be patched by creating a configuration patch file in the \App_Config\Include\zzz folder.
  
  
• To display not an empty error message:
  
  1. Open \sitecore\shell\client\Business Component Library\Layouts\Renderings\Forms\Uploader\Uploader.js (at about the 360th line)
  2. Add the following code sample (only the text in bold font):

     if (errorThrown === "abort") {
     that.app.trigger("upload-error", { id: data.__id });
     } else {
     if (!errorThrown || errorThrown.trim() === '')
     {
     errorThrown = jqXHR.responseJSON.errorItems[0].Message.concat(" See logs for more details.")
     }
     var errors = [{ Message: errorThrown }];
     that.app.trigger("sc-error", errors);
     that.app.trigger("upload-error", { id: data.__id, errors: errors });
     }
