Started to receive FailedToProcessFile errors

I have Duplicati running as a docker image on my Unraid configured to backup data to Backblaze B2. It has been running fine for months but over the last 2 weeks or so I have started seeing the same 3 errors over and over:

  • 2022-02-24 23:03:38 +00 - [Error-Duplicati.Library.Main.Operation.TestHandler-FailedToProcessFile]: Failed to process file duplicati-20220219T230000Z.dlist.zip.aes
  • 2022-02-24 23:04:50 +00 - [Error-Duplicati.Library.Main.Operation.TestHandler-FailedToProcessFile]: Failed to process file duplicati-i8774ce4c75f04e40a4b4313ec8c0d9cc.dindex.zip.aes

I’ve read a few forum posts on this error but I can’t really work out what files might be causing it in my instance so any insight would be greatly appreciated! Here are the logs from the live log data page:
