Hey @mukesh_behera,

There are few reasons why this exception occur.

UI Element present but may be inaccesible by bot due to some reasons.
Package versions, Web Extension

So for better investigation it will be helpful if you post a snap of your type into activity with properties and selector.

If you are automation is on a public website, then kindly post url as well.

Will be helpful, Awaiting your response

Thanks :slight_smile:

These words gave me confidence. I just want to know the cause actually. The exception does not contain proper information so little bit worry as I am new to UiPath. Thank you very much in advance.

PFA modified workflow given separately - (11.5 KB)

The actual issue is due to the new window getting opened during the process.

So the selectors inside the open browser getting messed up due to the close tab which was closing the first tab making the open browser session invalid resulted in an exception called one or more errors occurred.

Hope this helps.

Thanks once again :+1:
