“Something went wrong”
When the status pill shows Something went wrong, the snag is on our side — operators are notified automatically, and the platform’s own watchdog attempts recovery (it detects stalled and orphaned builds and retries them without you asking). If it doesn’t clear within a few minutes, send a message in the chat — “try again” is enough — or use the Retry action if one is offered. A build that fails at the very start (“the scaffold environment couldn’t start”) offers Retry directly; retrying is safe and loses nothing.The preview is blank or won’t load
Three ordinary causes, in order of likelihood:- It’s asleep. Previews pause after about 30 minutes of inactivity and wake in seconds when you return — you’ll see a Welcome back — bringing your workspace back online state, and your work is preserved. Just wait for it.
- The dev server needs a restart. Use the Restart button in the preview toolbar (it clears the build cache), then give the first compile a moment — the first build is the slowest one.
- The app itself crashed. The preview status pill will say so; ask the agent about the error in chat — fixing its own app is its job.
