In the past couple of days, we've had API processes that have ran fine for months, start to have issues. The error we seem to be most commonly seeing is error code 4000, "An unexpected error has occurred. Please contact the Support team at https://help.smartsheet.com/contact for assistance."
We're starting to sporadically see this for all variations for row gets, updates, creates, and moves. I've made a support case, but since I haven't noticed any public acknowledgement of any ongoing problems, I'm hoping someone else can chime in saying they've noticed some odd things the past couple of days.
Thank you!
