Created attachment 715877 [details] Testcase Steps: 1. Load the attached test case Expected: We should get an error callback with INVALID_STATE. Actual: An error callback fires with "3" as the parameter. This is probably due to the fact that we're not providing the enumerated name here and instead, providing the numerical enumerated equivalent. I'm going to go ahead and guess there's probably other ways to reproduce this pretty easily with other error codes. Let's fire a "useful" error code back at the developer.
