What are the best practices for RPA Exception Handling to prevent bot failure?

All answers to this question.

Professional RPA developers distinguish between System Exceptions (app crashes, network lag) and Business Exceptions (invalid data, missing fields). For System Exceptions, you should implement a "Retry" mechanism—often 3 attempts—before giving up. For Business Exceptions, the bot should skip that specific transaction, log the reason, and move to the next one. Using a framework like the UiPath Robotic Enterprise (RE) Framework is a lifesaver here because it has a built-in state machine designed specifically for robust error handling and logging. Never hard-code your delays; always use "Wait for Element" to make the bot dynamic.

How do you handle "Global Exceptions"? If the entire server goes down, can the bot notify the IT team automatically instead of just failing silently?

• Great question, Kevin. You should use a Global Exception Handler which is a specialized workflow that intercepts any error not caught by a Try-Catch. Within this, you can add an "SMTP Send Message" activity to alert the RPA Support team with a screenshot of the error and the log details. This ensures that even if a catastrophic failure occurs, the right people are notified instantly. Most enterprise-level orchestrators also have built-in "Alert" features that can trigger emails or Webhooks to Jira or Slack when a bot enters a "Faulted" state.

Make sure you use Log Messages at every stage. When a bot fails, the logs are the only way to reconstruct what happened at that exact millisecond.

• Absolutely, Brian. Good logging is the difference between fixing a bug in 5 minutes and spending 5 hours trying to replicate a random error.
