@uipath please support

@rajat_dhammi - have you tried adding individual rows via - add queue item activity?
pls do a for each row activity and pass row to add queue item and check the data available in queue.

in your datatable - what kind of data stored? is it a normal data type like strings/text or any blob/clob data?
