To troubleshoot the problematic stage:
  • Remove excess stages until problem stage is discovered. Once the stage is identified, try to reconnect the dataflow
  • Recreate dataflow from available back-ups.

If troubleshooting did not resolve your issue, contact technical support for further assistance.
