Getting Null responses

[PeterXuannanWu]

I am trying to get the sample project locator running, but currently met with an empty return from the query. What could be the cause? Below are my current application properties, am I using the correct URL?

Also, there seems to be some inconsistency between the sample LocatorRequest.json in README.md and the actual one. For example, field "RequestOption" is not supported by the JSON parser in LocationRequestRequest.java .

Any guidance on next steps to get the API call working is greatly appreciated!
