chromedriver not respecting `--headless` about fantoccini HOT 4 CLOSED

For anyone who might with this struggle as I did, you need to add browserName, it won't process the args at all otherwise. Not sure if same applies for other browsers but my guess is, it does. I thought the driver can figure it on its own, but seems like it needs this "hint".

        let cap: Capabilities = serde_json::from_str(
            r#"{"browserName":"chrome","goog:chromeOptions":{"args":["--headless"]}}"#,
        )
        .unwrap();
        let driver = ClientBuilder::native()
            .capabilities(cap)
            .connect("http://127.0.0.1:4444")
            .await
            .expect("failed to connect to WebDriver");

I think I found the issue! Should be fixed shortly in a new minor release :)

Wonderful, tysm!

Glad to hear you've found it useful! I'd also love to hear about any documentation shortcomings you may have come across so that we can improve things going forward! Documenting the use of serde_json::json! for capabilities for example would be a great addition.

As for the issue at hand, that's pretty weird. What happens if you run chromedriver with --verbose? Looking at the Chrome docs, what you pass in should be sufficient. Looking at this SO question, some people seem to be passing headless without --, and while that doesn't immediately make sense to me, it could be that that's necessary for some reason?
