Hi all,
I have a question for you.
I created a new model based on Payment model, a new mapping based on "Payment model mapping to destination ISO20022" and a new layout basesd on ISO20022 Credit transfer (IT) in a dev environment.
When i validate the layout without customization it show me an error "An error occurred during the request of file: 'ERCoveringLetter.xlsx'."
if I open th attachments, it shows me 3 attachments:

If i click on Open it give me an http 400 error.
Maybe after the restore of the database on my machine it was deleted.
How can i restore these files?
Thanks.
Nino
