Ambiguous uncaught error message

Line 206 in 64e61a4

application_root_plugin = application_info["config"]["applicationRootPlugin"]

This line assumes that application["config"] exists. If a key already exists for an application on SERVER and the application is deleted and replaced, when you try the command:

hp -p plugin_name -s SERVER

you get the error:

NoMethodError: undefined method '[]' for nil:NilClass

Instead, could a warning be added to highlight the fact that application["config"] does not exist?
