Hi @jamunatj ,

Could you let us know more details about the error?

When does it Occur ? Have you tried updating the Dependencies ?

Thanks for the response @supermanPunch

I didn’t update any dependencies & also got this exception in my production environment output result. I didn’t see the exception while running the BOT.

But the same script is working fine in the UAT environment. We are unable to find the exception why we are getting.

@jamunatj Do you use any Message Box activities or a Custom Dialog Box in the Process ?

Hello @jamunatj ,

As per the error it shows some error from the Message box activity. Plz confirm whether you have used some message box activity. Also is this an attended automation?

Please restart the uipath assistant and verify once.

Just compare the versions between the two bots/projects for the UiPath.System.Activities and upgrade the older one the newer one.

This parameter was introduced with a later version and currently not recognized as stated with the issue message

We have checked , But there is no message box.
