Hi @Sachin_Hatikankan

Have you bind the WIList to in_WIList in invoke Get Transaction Data?


Thanks for the resposne!
Yes gettransactiondata .

Still stuck with the same error

Hi @Sachin_Hatikankan
There Is issue in a arguments once check it You didn’t binded it properly.
Thanks & Regards

Hello @Sachin_Hatikankan the reason this error occurs is its not getting the value. so my solution would be first run your workflow in debug with slow step (1x) and check the locals pane and check whether all the vaiables and arguments are getting proper value or not this way you’ll find your error
