Cannot read properties of undefined (reading 'click') at <anonymous>:1:83

[Elanuroquesalta]

So, after cleaning some other errors, im still getting trouble with the code line where the JavaScript begins. Im still new to this language, so i cant find the source of the problem yet.

Any ideas?

There's a problem with your selector '#post-4101 > div > p:nth-child(4) > a:nth-child(4)', because the first element of the returned NodeList is undefined. Open the page in a browser and make sure it works there
