+  `ALREADY_EXISTS`: occurs for a copy step, if the overwrite option is not selected and a file with the same name already exists in the target location.
+  `BAD_REQUEST`: a general bad request: for example, a step that attempts to tag an EFS file returns `BAD_REQUEST`, as only S3 files can be tagged.
+  `CUSTOM_STEP_FAILED`: occurs when the custom step provided a callback that indicates failure.
+  `INTERNAL_SERVER_ERROR`: a catch-all error that can occur for a variety of reasons.
+  `NOT_FOUND`: occurs when a requested entity, for example a source file for a copy step, does not exist.
+  `PERMISSION_DENIED`: occurs if your policy does not contain the correct permissions to complete one or more of the steps in the workflow.
+  `TIMEOUT`: occurs when the execution times out.
**Note**  
 You can set the `TimeoutSeconds` for a custom step, anywhere from 1 second to 1800 seconds (30 minutes). 
+  `THROTTLED`: occurs if you exceed the new execution refill rate of one workflow per second.
