I want to set a bool when NULL is returned for a parse JSON property. There is no expression option available like its available in regular power automate.
I call a Power automate action from my power virtual agent bot. In the power automate action I query cosmosdb which returns an document. I then use parse json to parse the value returned by the action. If a property is null, set bool to false, if property is not null, set bool to true. Maybe there is a simpler way.
Appreciate your help.
Hi @SurajGuptha ,
You need to do this logic within the Power Automate flow and return only the TRUE or FALSE values as an output to your PVA Bot.
Today, it is not possible to define variables in the bots.
Does make any sense?
I wasn't able to see expressions inside of power automate in power virtual agents because of which I wasn't able to use the null expression. When I "X" the test bot screen, expressions and dynamic content started appearing.
