Error: Click with "Window Messages" is not supported for this element

Hello everyone,

I have a robot (automation) on Orchestrator. It is triggered every 4 hours on a Virtual Machine. I encountered an error in my logs.

Error: Click with “Window Messages” is not supported for this element. Please use other input method.

However, when launching the automation (robot) again from Orchestrator, this error is not reproduced. The robot is working fine.

Is it possible to know the source of this error. Why did this error happened and how to resolve this?

Note: I am not using “SendWindowMessages”. I’m using “SimulateClick” and “SimulateType” only.

Thank you.
