I try running this query but it seems to fail incorrectly.

doc.querySelector(".band:nth-of-type(3) .col-md-4:nth-of-type(2) h2")

Error Message:

TypeError: Cannot read properties of null (reading 'length')

When I run the same query in my browser while browsing the HTML page, it returns the <h2> element successfully.

    @taoqf It appears I'm still getting that error, I'm also getting it with this query
    .band:nth-of-type(3) .col-md-4:nth-of-type(3) blockquote p
    I do admit the query is quite complicated, is this something the library is not intended for?
