[Question #620963]: Amazon cloud backup exception on line 311

https://answers.launchpad.net/duplicity/+question/620963

Hello!

I am trying to perform a basic duplicity backup using the Amazon cloud backend. 

I start duplicity, I get prompted to authenticate and input the returned URL, which I do. The backup continues until it's supposed to upload to Amazon cloud, upon which it throws an exception. I am not sure how to interpret the exception and I can't seem to find much info on it either. From what I can see it has to do with oauth but I am not sure.

The exception is:

 Error: []

The command I'm running is:
duplicity -v9  --full-if-older-than 14D /media/BackupDrive ad:///Home_backup

The folder does exist on my Amazon cloud account and the authentication seems to go through. I'm using the latest backend for Amazon cloud and duplicity version 0.7.10. I'm running Debian jessie.

Any help would be greatly appreciated!
