Hi NagaSrinivas Medicherla.
I think the error is occurring because your factory is not returning a
promise, that's why the error says "Cannot read property 'then' of undefined
".
You need to *return deferred.promise;* and *resolve* or *reject* inside the
functions that you pass to the "*RestServiceCall*" function.
I hope this helps.
