com.fasterxml.jackson.databind.exc.MismatchedInputException: Unexpected token (START_OBJECT), expected START_ARRAY:

I am trying to save SearchAvailableRidesRequestOffline to android Shared Preferences. I need to deserialise the object to use it later on. While I try to deserialise it from json, I am getting this exception.

IOException

com.fasterxml.jackson.databind.exc.MismatchedInputException: Unexpected token (START_OBJECT), expected START_ARRAY: need JSON Array to contain As.WRAPPER_ARRAY type information for class com.mnox.webservices.core.ARequest at [Source: (String)"{ "request" : { .....
