Hi @rachida

Attach your workflow here.

I checked everywhere in your code, but I couldn’t find where you’re invoking this particular workflow.

[rachida]

in process transaction

Hi Rachida,

Please check your arguments. Bind them properly.

Thank You

Please check you arguments.
I think you have missed one mapping for it.
Also if you are on the old version click on export arguments button once

Apologies, @rachida

Yes. The problem is you’re using a browser object, but you’re not providing any reference to it. So it’s null at the moment. You’ll need to send the browser object as an input argument from the Main to the Process Workflow when invoking it.

[siddharth]

@rachida I’ve created an input argument inside Process.xaml for your browser object which you’ll be sending to “System1_Navigateto_WIDetails”.

I’ve used the Browser object variable (present in the Main) in the invoke workflow activity for Process.xaml as the value of the input argument “in_System1Browser”.

it shud fix the issue

[DanielaD (Daniela Dumitrascu)]

Hi Rachida,

The problem lays in the arguments that you used in invoke Process workflow.

These are the arguments in get transaction data (you obtain the data in datarow TransactionItem):

Then in Process, you do not send the data from TransactionItem, but from in_WIID, which is probably unassigned.

.

My advise would be to send argument in Process the same TransactionItem (datarow) and inside the workflow, if you need a value from that datarow, use in_TransactionItem(“WIID”).ToString

Daniela

Question:
Do you have open WIID in your test data?
I guess your process has already run once and completed.
