Object reference not set to an instance of an Object (Boolean Value)

I am getting an error while running the project

Flowchart.xaml (28.4 KB)

Hi @ramkrishna2k3,

from what I can see this should work if you have items in your queue - could you add a LogMessage before the Flow Descision to check wheter your transactionitem is nothing or if there is some data in it.

@ FrankSchikora
It also throws the same error

@ramkrishna2k3 if the log message also throws an error then your transaction item is empty.
Please check if there is actually something in the queue that get transaction item can fetch.
