I am very new to UIPath studio and trying to learn it. in one of the assignment i am working on using RE Framework i got stuck from last 2 days and spent around 12
hours to debug the issue. wherein it seems like my io_transactionData is pointing to null hence the loop for the transaction is not being processed.

Can anyone please help me to identify the issue?

Will really appreciate any help here.

Cheers…

The Extracted Datatable is set to ‘dtVendor’(variable, not argument)
But You passed ‘dtVendor1’(argument) to main workflow.
So there is no trasactiondata.

Since you used two dtVendor1(String variable, Datatable argument),
Change one of their name and set argument to Extracted Datatable output
