DataValidator

i have specified rules in Data Validator step but still i am facing issue

Kindly verify if appropriate error handling is in place for handling invalid data/records.

Error handling is not implicit in the Workflow.
Workflow must manage the control if data that is massaged contains error and proper action must then be processed.
If a step fails because of non-processable data, you can manage it with error hop so it goes a different route and correct the error or using try/catch logic.

Hope this helps.
