Breakpoint condition throwing error

Help Studio
,
1

In my REFramework project, I have put a breakpoint on the Check Stop Signal activity in the Get Transaction Data state. I added the condition TransactionNumber>1, and every time this activity throws the error

22.10.5+Branch.support-v22.10.Sha.79bc7c61a909d990afd07620b3005b3a35eb1f1b

Failed to evaluate condition: TransactionNumber>1
Executed condition returned: Exception has been thrown by the target of an invocation.

Why is this throwing this error?

Please click on open loga and check the full logs to understand…

Also can you check in variables if transactionnumber variable is initialized with 1 or is it removed

Cheers

TransactionNumber is initialized to 1

This is from the UiPath Studio log:

Hi joe.foster,
This is because the TransactionNumber variable is null. Please check if you are passing the TransactionNumber value as argument value to the desired workflow.

Cheers!

TransactionNumber is not null - it is equal to 1 - I can see that in the Locals panel.

However, for some inexplicable reason, it has decided to start working. I made no changes whatsoever…

Hi Joe,

If the error appear on GetTransactionData workflow then you need to use the in_TransactionNumber argument instead of TransactionNumber.
Cheers!

This is in the Get Transaction Data state of Main, NOT the GetTransactionData workflow.

Also, it has stopped working after it DID work for a short period. I made no relevant changes…

I have added a Log Message activity that shows that TransactionNumber is 1, and that the condition “TransactionNumber > 1” is false. It just seems that Conditional Breakpoint does not work as advertised…
