Solutions

1. Provide DesiredState as a JSON document describing the desired resource properties.

When it happens

Trigger: Thrown at src/main/java/io/github/hectorvent/floci/services/cloudcontrol/CloudControlService.java:103 when the library encounters an invalid state.

Common situations: Occurs when UpdateResource is called without DesiredState. Include the DesiredState JSON document describing the target properties.
