Continue session in Selenium cannot getAttribute() - selenium

Question

I have created a session in Selenium, re-use it by getting the session id, local_url and put into a different session. That means the new session will continue the original session. Function getAttribute() does not work on the continued session but if I put it in the original session, it works fine. I only face the problem with getAttribute() while other selenium functions such as getText(), getCss() worked well.
This is the re-use code:
RemoteWebDriver driver = createDriverFromSession(session_id, local_url);
System.out.println(driver.findElement(By.xpath(xpath)).getAttribute(attribute));
Output:
{message=unknown error: a.getAttributeNode is not a function
(Session info: chrome=67.0.3396.99)
(Driver info: chromedriver=2.40.565498 (ea082db3280dd6843ebfb08a625e3eb905c4f5ab),platform=Windows NT 10.0.14393 x86_64)}
Somebody please help me. Thanks!

Answer 1

I did face some issue --> message=unknown error: a.getAttributeNode is not a function
As i started debugging more - I figured out - Chrome is not using W3C Codec. So i changed code to reflect accordingly. Changed capabilities as well.
new W3CHttpCommandCodec to new JsonHttpCommandCodec()
new W3CHttpResponseCodec to new JsonHttpResponseCodec()
new RemoteWebDriver(executor, new DesiredCapabilities()) to return
new RemoteWebDriver(url, DesiredCapabilities.chrome())
This worked for my sample. Using selenium version 3.14.0 But believe it shouldn't matter.

The answer above worked for me, but I wanted to provide a little more context.
I originally looked for a way to re-attach to an existing Selenium session instead of opening a new one. I found the createDriverFromSession method (below) from another article on the web (I can't find it to link it). That article contained the code below. I commented out the lines that needed changed from the answer above.
public static RemoteWebDriver createDriverFromSession(final SessionId sessionId, URL command_executor){
CommandExecutor executor = new HttpCommandExecutor(command_executor) {
#Override
public Response execute(Command command) throws IOException {
Response response = null;
if (command.getName() == "newSession") {
response = new Response();
response.setSessionId(sessionId.toString());
response.setStatus(0);
response.setValue(Collections.<String, String>emptyMap());
try {
Field commandCodec = null;
commandCodec = this.getClass().getSuperclass().getDeclaredField("commandCodec");
commandCodec.setAccessible(true);
// commandCodec.set(this, new W3CHttpCommandCodec());
commandCodec.set(this, new JsonHttpCommandCodec());
Field responseCodec = null;
responseCodec = this.getClass().getSuperclass().getDeclaredField("responseCodec");
responseCodec.setAccessible(true);
// responseCodec.set(this, new W3CHttpResponseCodec());
responseCodec.set(this, new JsonHttpResponseCodec());
} catch (NoSuchFieldException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
}
} else {
response = super.execute(command);
}
return response;
}
};
// return new RemoteWebDriver(executor, new DesiredCapabilities());
return new RemoteWebDriver(executor, DesiredCapabilities.chrome());
}

I have also finally resolved this issue. It was something to do with W3C like mentioned above.
I was doing this:
ChromeOptions chromeOptions = new ChromeOptions();
chromeOptions.setExperimentalOption("w3c", false);
capabilities.setCapability("chromeOptions", chromeOptions);
I simply removed these caps and it worked as intended.
