A 503 from the /api/2.0/lakebox routes means the sandbox service is not deployed for the workspace's region, but the raw gateway error gives users no hint of that. Translate it at the API-wrapper level so every sandbox command reports the actual cause. Co-authored-by: Isaac
The SDK retries 503s for up to five minutes, so in regions without the sandbox service every command hung before erroring. Counting attempts in the ErrorRetriable hook (rather than racing a context deadline) halts the retry loop with the real APIError, so the translated message is deterministic. Since a few transient 503s are still retried, the message hedges between region unavailability and a temporary outage. Co-authored-by: Isaac

Changes
Sandbox API requests retry a 503 at most 3 times, then report:
the Databricks Sandbox feature is not available in your region, or the service is temporarily unavailable.Retries are capped by count (a per-request counter consumed in the client's
ErrorRetriablehook) rather than a deadline, so the final 503 deterministically surfaces as the API error. Other errors keep the SDK's default retry behavior.Tests
