AWS Deploy Failure

In trying to use the AWS Toolkit to deploy our .net application packages to elastic beanstalk we encountered a rather strange error:

[Error]: Caught exception probing for redeployment mode, Object reference not set to an instance of an object.
Failed to parse deployment configuration file: Deployment failed during post-processing of configuration settings.

Unfortunately this error told me very little and searching the web provided no resolve.

After speaking to Amazon it tuns out that the Frankfurt region does not support any version of the AWS toolkit prior to 2.3.4.

Updating the toolkit ultimately fixes the deployment issue.
