* [Issue #27077] Amazon Cloud Drive returns a HTTP 400 error (bad request) when a chunk appears to get lost on their end. The error code is returned as a JSON encoded
string inside a JSON encoded object as part of the 400 error. We now parse these, and process them accordingly. The user will now get a more informative
"Chunk N was not found" error in the UI. The data loss can be verified by logging into the Amazon Cloud Drive's web UI and attempting to download the
lost chunk. There is no mitigation for this issue, other than displaying a more informative error message, because the data is lost on Amazon's end.
