Tried using the na02 shard (which I don’t think I’m on since the IDE sends me to the other US one) and I got a 403 Forbidden instead of a 500.
Updated to 1.2.13.13 and got the same 500 error again.
Decided to try one more time while watching the logs at https://graph.api.smartthings.com/ide/logs not sure if I’d get any useful info. Aaannnd… it works.
