Error Handling and Retries in State Machines
Make your workflows robust. Learn Step Functions Retry and Catch fields, exponential backoff, and how to route failures to fallback states.
Failures Happen in Workflows
A Step Functions workflow chains many tasks. Any task can fail — a timeout, a throttle, or a thrown error. Built-in error handling lets the state machine recover instead of crashing.
Error Names
Step Functions classifies errors with names like States.Timeout, States.TaskFailed, and States.ALL. Your custom Lambda errors appear by their error name too.
