I am also having same issue, have click activity inside a for-each , it works for 2 to 3 iteration but after that get below exception

This is really Browser dependent. Just as the behavior of the browser changes as a manual person clicks the same button repeatedly (due to cookies, trackers, etc) when the robot clicks the same button repeatedly the browser will behave differently.

A simple workaround I have found is to simply use the Refresh Page activity for that page to reload the browser, but there may be other solutions based on unique cases.

I have it on for a send email activity, no browser involved…

5

and i have for reading PDF no browser involved either

Please click details on error message and share the error screenshot. :slightly_smiling_face:

I got the same error like above…already put “Refresh Browser” Activity…is any other solution?

I got the same problem. And It doesn’t happen every time when I run the same robot. Is it Uipath product issue or bug?

Value does not fall within the expected range.

This sounds like your workflow is not set up properly. Without a screenshot or more info, it’s impossible to determine the exact cause.

Hello,
I am having similar issue while using click activity. I can’t refresh browser since it’s a prompt I am trying to click on. Here is the error. I am trying to click on ‘Yes’

Hi,
I resolved issue but for benefit of future readers. Here’s what the issue was:

  1. My click activity was inside attach browser window and selector for attach browser window was in_argument which was null. When I passed correct value error resolved.
