Hello !
I am trying to use the “Throw” activity and within a workflow invoked inside of a try-catch activity.
The robot keeps giving me this error message :
Anyone has a clue of what is happening ?
Thanks a lot
what are you trying to do in throw activity @Mushu?
@HareeshMR
Hello. I am trying to throw an “Invalid Operation Error” like this :
Before the throw activity, I assign the variable like this :
with out_InvalidOperationException = New.system.InvalidOperationException
I hope it’s a bit clearer.
I hope the way you are assigning is
out_InvalidOperationException = New system.InvalidOperationException
As you are trying it with a null value, you are getting the above error.
In order to throw the invalidoperationexception, wherever you are getting that error, assign it to a variable and then use that to throw and you are trying it alone without any proper exception.
If you want to throw a particular text, then you can do that above using business rule exception 
Hope I’m clear. Let me know if you have any doubts
@HareeshMR
Thanks for the fast reply.
I tried with the following :
As you said, I assigned
Out_InvalidOperation = New system.InvalidOperationException
And then I Threw :
Out_InvalidOperation
The same error keeps popping up…

in throw exception itself
mention as
New System.InvalidOperationException(“Error occured”)
and if we want we can use out_invalidoperation with a variable storing that exception error
i hope we dont need it if we are using throw activity
Cheers @Mushu
What I mean to say is, you don’t need to initialize and assign a value to the variable, Use try catch activity @Mushu, in the drop down select the required error and it will stored in a variable exception. then use throw activity to display the error as below. If you want to throw your own message in throw activity, you can throw the business rule exception
