Yesterday (October 13) a SmartApp which had been running for 2 years broke down.
I tried to execute it from the IDE, but got obscure error messages (2 different).
I contacted support, with a strong suspicion of some SmartThings cloud overload, but once they saw ācustom SmartAppā, they declared it was not their problem !
I posted my problem in this other thread : Cassandra timeout during read query?, since one of the 2 error codes I got was a āCassandra timeoutā.
Interestingly (?!!), up to now, this periodic smartApp would often fail to schedule (it runs every 5 days), but when it did it executed properly. Now it schedulesā¦ and aborts !
Note sure I would label that as āprogressāā¦
