Im getting this error: “Error getting transaction data for Transaction Number: 1. Value cannot be null. Parameter name: source at Source: If” in Assignment nr. 1 from Advanced Level and i don’t know where is the mistake
please initialize the TransactionNumber with 1 and try once again.
based on that you are page numbers processed, if you leave it null it throws an error.
are you in Assignment 1 or 2…?
if its assignment 2 then remove that activity which throwing error, its not needed.
i guess you have not passed arguments to GetTransactiondata(), can you verify once…
in_transactionNumber = TransactionNumber
This is my Get transaction data… i don t know where i need to change the values
GetTransactionData.xaml (10.9 KB)
GetTransactionData.xaml (10.1 KB)
i have sent mine, check and update where ever needed.
it’s the same yours with mine. Anyway Thank you very much.
in that case put a breakpoint to Gettransactiondata workflow and use debug mode to see whats the prob…
Please verify that you have value in in_WIList in GetTransactionData.xaml if there no value see that you have extracted and sent the WILIst items correctly. In InitState like this
Thank you very much i already fixed. That was the mistake. Thank you all for your help.
I am facing same transaction number issue can any one please help on this.
I am successfully logged into ACME application, clicked on ‘work Items’ , collected all the data stored in a data table ,filtered with ‘WI5’ and ‘open’ status and filtered items stored in WIList .
Below are the argument for ‘Get Transaction Data’ WorkFlow
When I am entering into ‘Get Transaction Data’ work flow my condition is failing due to below error.
“Error getting transaction data for Transaction Number: 1. Value cannot be null. Parameter name: source at Source: UiPath.Executor”
exactly at below condition script is failing
You have not completed the argument binding.
- Collect Data and create out argument WIList [correct]
- Invoke System1 Extract Work Items - map argument WIList to a locally created variable WIList in Main(same type)
- Now map the WIList variable here
Without this in below if in_WIList is null, hence the warning
Thank you for help.
