When importing data for attachments in the catalog module, if the said attachment is over 50 characters long, the string is cut, leading to no updates for this data.

1 - create an attachment with a name over 50 characters long, for instance, "This is a very long attachment name that is created to test an issue".

2 - associate it to a product

3 - export this data using the UI /admin/Site/Relatorio_Skus.aspx

4 - Check the column related to this and it will be displayed as "This is a very long attachment name that is create" (exactly at 50 characters).

5 - you will need to manually adjust this information if you want to properly import it

Update attachments via API, UI, or manually change their incorrect string in the sheet.
