ERROR object

The JSON ERROR object is sent in response to a request that can not be executed correctly.

Object definition

Field name	Type	Status	Description
`Result`	string	always	Constant value: `error`
`Message`	string	option	A string that explains the error.
`Error`	string	option	The error code (numeric or constant name) if available (for PC/SC errors mostly).

If the Result field is success, not error, this is in fact a SUCCESS object!
