Assignment 2 dispatcher- can't find more transaction data

Hi now I’m struggling with assignment2 for 3days.

first of all, my system 1 login, go to the work item are fine and work well.
but when it should data scrap all the page of work-item, it just gone
and show “Process finished due to no more transaction data” message.
and also
“message”: “Error getting transaction data for Transaction Number: 1. Object reference not set to an instance of an object. at Source: Anonymously Hosted DynamicMethods Assembly”,
“level”: “Fatal”,
“logType”: “User”,
“timeStamp”: “14:00:30”,
“processVersion”: “1.0.0”,
“jobId”: “00a44915-e840-4372-996c-27d8f027c472”,
“robotName”: “yeeun”,
“machineId”: 183252,
“fileName”: “Main”,
“logF_BusinessProcessName”: “Framework”
show this message before the 'no more data’message.

i’m trying so hard to figure that, but I can’t find it.
Can anyone help?

Hello @esther30
welcome to our community

just check you are passing transactionItem pass in argument in correct way


hello thanks for ur answer @sandeep13

I made that value already first time and check double after ur comment.
but it still stuck in that way with same error message.
what should I do…?
I want to upload my whole workflow but i’m new here, so can’t upload it/…

Hello @esther30

  1. first you just check datatable value out_dt.Rows.count in where you scrap all workitem

  2. after that just check passing argument in correct way where you invoke workflow

  3. check variable and argument in init section where InitAllApplication invoke

  4. check where GetTransaction Data workflow invoke

  5. after that check getTransaction workflow

hope its help


Hello Sandeep13!

I did all what you write, but I have problem. In getTransaction workflow, I get all time only first row from my DataTable…
How can I decide this problem?

in success
assign TransactionNumber=TransactionNumber+1


Thank You very much)))
