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.

Actually I am new to D365FO.

Is it required to register my web portal URL in D365FO through which I am calling services of D365FO?

It can be anything actualy its hard to determine problem with that. I can only suggest you put more log your api and track whats going on

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.
