“Next Transaction, get Data: Object reference not set to an instance of an object.”


Anyone help me out resolve this issue…

Thanks, Advance

Hi @Aditi_rathore

Can you check whether the input argument io_ transactionData is assigned with a datatable that has data when invoking the get transaction data xaml file?

It seems like it is not assigned with a value and that’s why you are getting the error.

If it is assigned in the invoke workflow activity, then you might need to check whether that mapped variable is getting assigned with a value in the activities that are executed prior to that…

@Lahiru.Fernando
Yeah

@Aditi_rathore

I see that this is invoked inside an if activity. Does this if activity execute for each iteration in the REFramework model?

it looks like, if at one iteration, if this part doesn’t get executed, your io transaction Data variable will be null

@Lahiru.Fernando
No it’s not iterated
