What happened:
A compatibility change in Zendesk’s Agent Workspace exposed a latent issue in our app’s save flow. One code path didn’t return an explicit result and we also relied on a deprecated event. In this combination, Zendesk kept waiting and the save timed out.
What we fixed:
We immediately reached out to Zendesk and, together, pinpointed a compatibility change in Agent Workspace that caused the timeouts. We shipped a fix the same day and verified it in Agent Workspace and the classic UI. We'll make sure this won't happen again.
