> In summary: not a bug in Wyvern, but maybe Wyvern could be a bit more verbose about logging what it's doing, to make errors easier to diagnose. Should I file an issue about that?
Yes, please do so. Thanks for the suggestion— I’ll definitely make it clearer when there are errors in the request and when this error occurs specifically, I’ll include a message explaining how to fix it. Thanks for doing more than your fair share of the investigating on this bug, as well!
