Failed: Object reference not set to an instance of an object

I am unable to perform a restore on my data. I receive the following error.

Failed: Object reference not set to an instance of an object.
Details: System.NullReferenceException: Object reference not set to an instance of an object.
at Duplicati.Library.Utility.FilterExpression.FilterEntry…ctor(String filter)

at Duplicati.Library.Main.Operation.ListFilesHandler.Run(IEnumerable1 filterstrings, IFilter compositefilter) at Duplicati.Library.Main.Controller.RunAction[T](T result, String[]& paths, IFilter& filter, Action1 method)

This happens on multiple machines. Any help would be appreciated!

The error message seems to indicate a filter problem.

Can you try to export the backup to commandline, and post the filters here?
