Hi @muktern8n Welcome!  
The error names your counts, not your progress, so this is the payload rather than stale backend state. `batch_size` is the one value that doesn’t match Step 2.7, which uses 5. Set `BatchPriorityOrders` to a batch size of 5, re-run the whole workflow in one go, and finalize with `batch_size: 5`.  
See this:
