Crash at get_midpoint

[makorne]

Hi!
Thank you for great crate!

After several successful click at the same button, something changed on page and:

thread 'main' panicked at 'calledOption::unwrap()on aNonevalue', /home/den/.cargo/git/checkouts/rust-headless-chrome-fd32a97e7a7fa8b4/60b775b/src/browser/tab/element/mod.rs:510:51

let raw_quad = quad.quads.first().unwrap(); << this unwrap

Buttons div changed to <div style="display: none;">

Hi @makorne, are you using CSS or XPATH selector to find such button?

[makorne]

Hi @masc-it

while let Ok(button) = tab.wait_for_element(".button1"){ 
    match button.click() {
     ...
    }
}

I had the same issue trying to click on a button

thread 'main' panicked at 'called `Option::unwrap()` on a `None` value', C:\Users\me\.cargo\registry\src\github.com-1ecc6299db9ec823\headless_chrome-1.0.5\src\browser\tab\element\mod.rs:510:51

Looking in the code, the line @makorne pointed :
let raw_quad = quad.quads.first().unwrap();
suggests that the quad array returned by the GetContentQuad method was empty
Looking in some DOM docs (and asking chatgpt) it could be that this happens if the element we are trying to click is not visible.

I've checked with headless(false) what could be blocking the view of the button and it turns out that it was hidden behind a cookie popup.

adding

tab.wait_for_xpath(r#"//*[@id="bnp_btn_reject"]"#)?
    .click()?;

fixed the issue for me.

Maybe we could change the code to something like this :

let raw_quad = quad.quads.first().except("tried to get the midpoint of an element which is not visible");

to get a more helpfull error than

'called `Option::unwrap()` on a `None` value'
