I tried a couple of minutes layer and then things worked. Maybe add a try..except block to print out more information that could be useful for debugging?

Thank you, @dcherian! Did this error persist or did it end up going away? (Never mind :). I just saw you mentioned things worked after another attempt)

This has been addressed in #77
