@Team: Invalid issue is very common in UIPath, don’t worry here is the solution.
1- Change the web browser to inspect the element, in my case I was getting error invalid UI and not able to capture the text using “Get Full Text” when I was using chrome browser. When I changed browser from Chrome to Mozila, then I was able to capture text.
And still getting an error Invalid “UI node error”, but that “error:” was not important for me as I was able to capture text.
2- And please make sure the extension is installed on both chrome or Firefox.
