[🐛 Bug]: Selenium Manager is encountering an issue with the setProxyAutoconfigUrl() method.

[dineshkumar-kanniyammal]

What happened?

An error occurs when trying to set a proxy auto-configuration URL using setProxyAutoconfigUrl() in a FirefoxOptions object. The geckodriver is not able to launch, and the following error is thrown:

org.openqa.selenium.remote.NoSuchDriverException: Unable to obtain: geckodriver, error Command failed with code: 65, executed: [--browser, firefox, --browser-version, 128.0, --proxy, http://web-proxy/proxy.pac, --language-binding, java, --output, json]
error sending request for url (https://product-details.mozilla.org/1.0/firefox_history_major_releases.json)
Build info: version: '4.26.0', revision: '69f9e5e'
System info: os.name: 'Mac OS X', os.arch: 'x86_64', os.version: '14.7.2', java.version: '17.0.5'
Driver info: driver.version: FirefoxDriver

How can we reproduce the issue?

FirefoxOptions firefoxOptions = new FirefoxOptions();
firefoxOptions.setBrowserVersion("129.0");

Proxy proxy = new Proxy();
proxy.setProxyAutoconfigUrl("http://web-proxy/proxy.pac");
			
firefoxOptions.setProxy(proxy);

new FirefoxDriver(firefoxOptions);

You need to configure your PAC Proxy properly so it can access that URL https://www.selenium.dev/documentation/selenium_manager/#connectivity-issues

[dineshkumar-kanniyammal]

FirefoxOptions firefoxOptions = new FirefoxOptions();
firefoxOptions.setBrowserVersion("128.0");
Proxy proxy = new Proxy();
proxy.setProxyAutoconfigUrl("http://web-proxy/proxy.pac");
firefoxOptions.setCapability("proxy", proxy);
new FirefoxDriver(firefoxOptions);

Even though we added the proxy.pac URL using the setCapability flow, we are still facing connectivity issues with Selenium Manager. How can we resolve this? Could you also share a sample proxy.pac URL configuration with Selenium Manager?

I did not mean to add the proxy as a capability, which you already do. I meant the PAC configuration itself. I cannot troubleshoot that for you.

System.setProperty("SE_PROXY", "http://web-proxy/proxy.pac");

I tried using Selenium Manager with an environment variable for a PAC proxy, but it didn't work. Could you please provide more details about PAC configuration or share any relevant documentation for configuring PAC with Selenium Manager?
