javascript - document.evaluate with XPath only working if I inspect element first

Question

All new to JavaScript and experiencing a frustrating problem.

So basically I'm trying to achieve a click as part of an automation process. Here's what I'm doing:

document.evaluate('//a[@aria-label="Salgsfakturaer" and @role="menuitem"]',document.body,null,9,null).singleNodeValue.click() 

This works great from the console but ONLY if I've gone to the trouble of inspecting the element first! If I reload the page and fire off the same I get an error. Again I can then go and inspect the element and try again - and it works!

So what I'm thinking, and I'm no JavaScript expert, is that it has something to do with the main content being in an iframe and that the source is not loaded initially (only when I go to inspect). If this is a correct assumption, how can I handle this?

Thanks in advance for pointing me in the right direction.
