Well, you see... I don't really know graph-ql, so your guess as to what went wrong is as good as mine.

joking aside, this is probably due a rate throttling. Try setting your betting speed in the advanced bet settings screen (even if you're using the programmer mode) and see if it still happens. Trying to reset seed/withdrawing/tipping could also cause this error. If none of these work, please send me the dicebotlog.txt file to contact@seuntjie.com
