Unrecognized platform: mac-unknown-64bit

[RajAsapu]

I am getting the "org.openqa.selenium.WebDriverException: Unrecognized platform: mac-unknown-64bit"

Same exception is occurring for the linux.

while running my test with phantomJs . Below are the configurations i am using
Dependencies

 compile group: 'org.jboss.arquillian.extension', name: 'arquillian-phantom-driver', version: '1.2.1.1'
 compile group: 'org.seleniumhq.selenium', name: 'selenium-server', version: '3.4.0'
 compile group: 'org.seleniumhq.selenium', name: 'selenium-java', version: '3.4.0'

To Open browser:
try { String[] cli_args = new String[]{"--ignore-ssl-errors=true", "--debug=true"}; DesiredCapabilities capabilities = DesiredCapabilities.phantomjs(); capabilities.setJavascriptEnabled(true); capabilities.acceptInsecureCerts(); capabilities.setCapability(PhantomJSDriverService.PHANTOMJS_CLI_ARGS, cli_args); driver = new PhantomJSDriver( ResolvingPhantomJSDriverService.createDefaultService(), capabilities); } catch (IOException e) { e.printStackTrace(); } ((JavascriptExecutor) driver).executeAsyncScript( "window.setTimeout(arguments[arguments.length - 1], 30000);"); driver.manage().window().setSize(new Dimension(1280, 1024));

Please provide the complete log that contains the exception stacktrace, we have to know where it was thrown from.

I've just stumbled upon exactly the same problem. Here's my stacktrace (for JS app):

@bushee I can't see from your log that you have the same problem ("Unrecognized platform")

[RajAsapu]

@barancev : Below is the log

[RajAsapu]

Phantom Js is working with Selenium 3.0.1 and setting the platform using

capabilities.setCapability("Platform", Platform.ANY);

instead of

capabilities.setPlatform(Platform.ANY);

[nkonev]

I have same error:

This is the code from RemoteWebDriver.startSession()

protected void startSession(Capabilities desiredCapabilities) {
   Map<String, ?> parameters = ImmutableMap.of("desiredCapabilities", desiredCapabilities);

   Response response = execute(DriverCommand.NEW_SESSION, parameters);

   Map<String, Object> rawCapabilities = (Map<String, Object>) response.getValue();
   MutableCapabilities returnedCapabilities = new MutableCapabilities();
   for (Map.Entry<String, Object> entry : rawCapabilities.entrySet()) {
     // Handle the platform later
     if (CapabilityType.PLATFORM.equals(entry.getKey()) || "platformName".equals(entry.getKey())) {
       continue;
     }
     returnedCapabilities.setCapability(entry.getKey(), entry.getValue());
   }
   String platformString = (String) rawCapabilities.getOrDefault(CapabilityType.PLATFORM, rawCapabilities.get("platformName"));
   Platform platform;
   try {
     if (platformString == null || "".equals(platformString)) {
       platform = Platform.ANY;
     } else {
       platform = Platform.fromString(platformString);
     }
   } catch (IllegalArgumentException e) {
     // The server probably responded with a name matching the os.name
     // system property. Try to recover and parse this.
     platform = Platform.extractFromSysProperty(platformString);
   }
   returnedCapabilities.setCapability(CapabilityType.PLATFORM, platform);
   returnedCapabilities.setCapability("platformName", platform);

   if (rawCapabilities.containsKey(SUPPORTS_JAVASCRIPT)) {
     Object raw = rawCapabilities.get(SUPPORTS_JAVASCRIPT);
     if (raw instanceof String) {
       returnedCapabilities.setCapability(SUPPORTS_JAVASCRIPT, Boolean.parseBoolean((String) raw));
     } else if (raw instanceof Boolean) {
       returnedCapabilities.setCapability(SUPPORTS_JAVASCRIPT, ((Boolean) raw).booleanValue());
     }
   } else {
     returnedCapabilities.setCapability(SUPPORTS_JAVASCRIPT, true);
   }

   capabilities = returnedCapabilities;
   sessionId = new SessionId(response.getSessionId());
 }

There are 2 issues here:

1. PhantomJS is returning a platform like mac-unknown-64bit, linux-unknown-64bit or windows-10-32bit. None of these values will ever be parsed by Platform.fromString(), so a WebDriverException is thrown.
2. Platform.fromString(platformString) may throw a WebDriverException, but the try block only catches a IllegalArgumentException. Hence the WebDriverException bubbles up and stops the application.

This is a dirty hack that will get you out of trouble for now:

I see also this error on selenium-server-standalone-3.6.0.jar. On selenium-server-standalone-3.5.3.jar it's ok.

Thanks @MrEfrem, the problems resolved after changing to version 3.5.3

[RajAsapu]

@barancev : @MrEfrem says that it is fixed in 3.5.3 not 3.6.0, which means it has to be fixed in the latest version . I expect this issue to be open until its resolved in the latest version .
