Error (500)(unchecked_execution): java.lang.NullPointerException when doing a get on an entity

[#1]

Hi

I've been getting this error at times when I am doing a get request on an entity. It works sometimes and sometimes gives this error

Error (500)(unchecked_execution): java.lang.NullPointerException

There are two asynchronous calls being made and either one of them fails at times. About 50% of time I get the null pointer exception. Any idea why this would be happening? I see the same error when I try to open the entity from the Apigee App Services UI too.

Thanks
