Unfortunately we know nothing about your services, therefore finding bugs in them is extremely difficult. You, on the other hand, can debug your code, so you're in a much better position to find out where things fail.

Just a guess. Because the operations is successful, but it failed to find records, a possible explanation is that you're now trying to fetch data from a different company. If it's not the case, I would stop guessing and start debugging.

It seems that you also have another bug in your web service - I don't believe that it should return 200 if it actually fails. You see that you have no idea about what happened if your web service lies about the success.
