Only legacy OSS protocol dialect is supported

[RouR]

I have issue with library Selenium.WebDriver 4.0.0-alpha03

This lib is not campatible with selenoid 1.9.3 after removing legacy OSS protocol dialect - check this commit SeleniumHQ/selenium@8767cd3#diff-5fedfeb3060c9b589bc5ac90334761caL1073

This appears as error

{"status":13,"value":{"message":"Requested environment is not available"}}

@RouR that means you are specifying capabilities incorrectly. Could you please show your capabilities?

[RouR]

var browser = new ChromeOptions();
browser.BrowserVersion = "79";
var driver = new RemoteWebDriver(options.HubUrl, browser.ToCapabilities(), options.BrowserTimeout);

This code is ok with Selenium.WebDriver 3.141.0

@RouR Selenoid supports w3c-style protocol. Anyway, give me some time to check (will do with Java client of the same version, have no C#).

[vania-pooh]

@RouR for me just the same version of Java client works like a charm. Please try to print request and response body:

CommandExecutor commandExecutor = new HttpCommandExecutor(...);
WebDriver driver = new RemoteWebDriver(commandExecutor, browser);

I'm not a C# developer, so there should be the way to make .NET standard library print JSON request and response body. So far as I can see in this class Selenium is using standard System.Net.Http package to make HTTP requests.

This work:

{"desiredCapabilities":{"browserName":"chrome","browserVersion":"79","goog:chromeOptions":{"args":[]}},"capabilities":{"firstMatch":[{"browserName":"chrome","browserVersion":"79","goog:chromeOptions":{"args":["--enable-dom-distiller","--distillability-dev"],"localState":{"reader.parse-on-load.enabled":true}}}]}}

{"value":{"capabilities":{"acceptInsecureCerts":false,"browserName":"chrome","browserVersion":"79.0.3945.79","chrome":{"chromedriverVersion":"79.0.3945.36 (3582db32b33893869b8c1339e8f4d9ed1816f143-refs/branch-heads/3945@{#614})","userDataDir":"/tmp/.com.google.Chrome.WzrN4V"},"goog:chromeOptions":{"debuggerAddress":"localhost:40617"},"networkConnectionEnabled":false,"pageLoadStrategy":"normal","platformName":"linux","proxy":{},"setWindowRect":true,"strictFileInteractability":false,"timeouts":{"implicit":0,"pageLoad":300000,"script":30000},"unhandledPromptBehavior":"dismiss and notify"},"sessionId":"f8d46813f4b203e76f6cfea31ec7cd37"}}

This not work:

{"capabilities":{"firstMatch":[{"browserName":"chrome","browserVersion":"79","goog:chromeOptions":{"args":[]}}]}}

{"status":13,"value":{"message":"Requested environment is not available"}}

See missed desiredCapabilities

@RouR ok, then this is because of missing firstMatch support in Selenoid. Closing this as a duplicate of #450.

[vania-pooh]

@RouR yesterday we merged support for firstMatch. Could you try whether it works with aerokube/selenoid:latest image?

[RouR]

Yes, it work!
Thanks a lot

[vania-pooh]

@RouR ok, this will be released during next days.
