I am trying to find 3 elements on a page by Find Element activity and store there output as arguments so that i could use them in other activity.
When i run the workflow, elements are identified but at the end of execution i get following error
Source: Newtonsoft.Json

Message: Unable to find a constructor to use for type UiPath.Core.UiElement. A class should either have a default constructor, one constructor with arguments or a constructor marked with the JsonConstructor attribute. Path ‘Output.loginbutton.Selector’, line 1, position 105.

Exception Type: JsonSerializationException

I only have three activity of Find Element in workflow


#2

Are you using any OutArguments and workflow is invoked with isolated flag or via LaunchWorkflowInteractive?

Looks like you’re trying to pass an object that cannot be serialized across process boundaries.
