How can I correct the error
Failed to process file duplicati-xxx.dindex.zip.aes => Si sono verificati uno o più errori.
(one or more errors have happened)

and the error:
Failed to process file duplicati-xxx.dblock.zip.aes => Il valore non può essere null.
Nome parametro: uriString
(value can’t be null - parameter name: uriString)

?

That’s a bit if a wide open question, perhaps some more detail might help…

  • Is there any more detail associated with the error (clicking on the error line in the log often expands to show more information)?
  • What version of Duplicati are you using?
  • What destination are you using (local, LAN, Google Drive, etc.) and how are you getting there (drive letter, UNC, FTP, WebDAV, etc.)?

Happened another time just now, during a backup job to Mega. What’s wrong?

Edit: this time the log does not contain any “failed to process file” occurrence.

Here is the completed text sent via email:
