Errors Preview

Errors Preview centralizes problems raised by workers in a run.

Typical Error Types

• Network/API failures (timeouts, 4xx/5xx responses)
• Validation errors (missing required parameter)
• Data shape mismatches
• Rate limiting warnings

Using the View

• Open Errors Preview from the workflow or worker context.
• Each entry includes a message and often a worker reference.

Resolution Steps

1. Identify the first failing worker (later errors may cascade).
2. Open its parameter window and adjust configuration.
3. Re-run and re-check Data Preview before moving forward.

Best Practices

• Fix upstream errors first—they often resolve downstream noise.
• Keep an eye on recurring transient errors; consider adding retries (if available).
