I have made a bot that asks a bunch of questions and then using the variables calls flow to send an email. The problem is that some variables are optional for the user (the chat flow is made like that) and when some variables are not provided, the flow call is executed and the questions are asked again.
Is there any way to assign variable a null value?
Hi @ankit3 ,
Can you take some pictures of your scenario?
But side your pictures, you can see if this topic help you: https://powerusers.microsoft.com/t5/Power-Virtual-Agents-Forum/Conditition-to-test-a-variable-for-an...
The solution is: "[...] are you trying to handle a return variable from a flow and do a condition in PVA based on that? I had the same issue and I had to add some logic in the flow to set the value of the variable to "NotFound" and then pass that back into the PVA so that the condition had something to select. Yes i know, workaround to fix a simple feature gap but you know... Let's be agile!"
Thanks for your reply.
Attaching screenshot of the PVA where I'm calling flow. You can see there are around 8 variables. The flow is executed perfectly if all 8 all present but of user chooses not to provide the "CompanyName", the flow is not executed and user is asked to provide "CompanyName" again. What I'm asking is that, is there any way I can identify if a variable is empty and if yes, assign "Null" to it so that flow can be executed?
