Please provide a test case that demonstrates the issue so we can fix it.
Comment 2 Grigory (Playtika) 2015-10-01 13:53:04 UTC
Nullref! What repro do u need ? Check the code, ensure that u throw proper exceptions.
Comment 3 Rodrigo Kumpera 2015-10-01 15:00:17 UTC
Can you provide the code that initiates this web request?

It's very hard to tell what situation is triggering this error. Without actually knowing what you're trying to do, it's hard to tell how our code is misbehaving.
