So i was on the Build a REFramework Project with Tabular Data part and tried to make some changes in the GetTransactionData workflow as according to the academy videos
well when i debug the project i get error on the if activity that said "if: object reference not set to an instance of an object."
so then i check that if both values im comparing is holding values or after adding a break point in the imidiate pannel i see that the io_dt_TransactionData is not holding any value and refring null though its should give the count of the no of rows in the datatable
first if condition where it checks that if the io_dt_TransactionData is holding any data or not
second if condition where it checks that the transactionnumber is less then equals to the transactiondata rows count
in the final image you can see my imideate pannel
