The typo fix makes sense, though looking at this code now I strongly suspect this is not something we should be doing. That exception should not be wrapped and definitely not into a runtime exception.

Thanks for submitting this!

Our test also appears to be validating the error message with the typo. Can you update the test cases as well?

[yebrahim]

Done.

[chingor13]

Sorry, there's one more failed test

[yebrahim]

Done. Editing code on Github... :)
