Argument 'Operand' of activity 'Not<Boolean,Boolean>' is bound to an expression that contains activity 'InvokeMethod<Boolean>'. 'InvokeMethod<Boolean>' can cause the expression to idle during evaluation

Hi,

Can you share screenshot of activities which is caused by these warnings?

Hi,

There seems no error in workflow even though there are validation errors.

If possible, can you share your Process.xaml as a file?

Hi @Prem_Chand1

I too noticed this warning and it started appearing after upgrading from UiPath.UIAutomation.Activities = 21.4.4 to UiPath.UIAutomation.Activities = 21.10.3

On quick check i found ‘On Element Appear’ and ‘On Element Vanish’ activities triggers the warning

Once you downgrade the package to 21.4.4 this warning will disappear.

Steps to reproduce

  1. Upgrade to UiPath.UIAutomation.Activities = 21.10.3
  2. Drag and Drop On Element Appear or On Element Vanish

Studio version used : 2020.10.4
