I am trying to get a text from an invoice, from invoice table and I made an selector for every row in the table, but when I want to get the text from the row I will get just empty string. When I want to use Highlight to see the element it tells me “Highlight : The UI element you are trying to highlight is valid, but not visible.”. What can I do in this situation?
