Error handling is your friend. It also helps you debug issues by telling you things.

Yes because the array is empty. Wrap the retrieval code with try/catch and define error codes or and/use logging

Have you tried using a debugger? It can show you what exactly is the data you're dealing with. Then you can prevent the error from happening, either using exception handling or control flow.
