Hi Gowthami,

I assume you are talking about the error "at least one allowed role must be selected if the microflow is used from navigation, a page, a nanoflow or a published service". It means that you have your security set for your app, but this flow that is giving the error does not have any allowed roles. If the flow is only being triggered by your system or in a subflow you don't need to set allowed roles. However if you directly trigger it from navigation, a page, a nanoflow or a published service you will have to apply allowed roles for the flow.

To solve this, open the designated microflow. Click on a blank space outside of your canvas and in the properties of your flow, on the "allowed roles" selector, add a module role for this flow.
