Thank you, @nikpivkin !
Could you please add a test case that demonstrates the problem?

In the past, I've found it really handy to demonstrate json.Unmarshal errors by forcing the data to be something bogus for JSON like {].

@gmlewis Hi! Fixed! The initial fix was that the error did not return when the response status was 202. (nil returned)
