To investigate, start DevTools to review your HTML; either hit the F12 key, click on “Open DevTools”, then use either CTRL + SHIFT + C or click on the first icon within DevTools that looks like a rectangle with a pointer moving into it. Then move your mouse pointer to an element. Click on the element to have the HTML display that element. Or you can hover over the element to have the information displayed.
Another method that may work, you can right click on an element and choose, Inspect. Then choose Inspect again to move the HTML right to your element.
This will give you the information if your tag is an <a> or a <select>. I think now it is an <a> and the <select> was you changing the pathway. If your application does not use <select>, then you will not be able to use the “selectOptionByLabel”, “selectOptionByValue” or “selectOptionByIndex” but will have to, in all likely, “search” for your respective item with some code. We can help with this, but will probably need to review your HTML.
Additionally, do you have “wait” statements within your code to delay when you switch pages etc.? if you are “[g]etting invalid element state error”, then this may be the cause.
