Uncaught Error on retrieving license

Hi all, I′m getting a Uncaught Error when trying to retrieve a licence with non-existing license number, Internal Server Error. However, when I try to do the same with “activate” call, response is correct and JSON message is sent back normally with message about non-existing license key.

What can be wrong? I′ve tested it in Postman, just for testing purposes. It should be bulletproof, consumer may type the wrong license key, taht is a normal thing.
