Serenity Devtools driver issue

[Vijay2871]

When i try to extract info from console using devtools I'm getting issue in driver showing null
code snippet:

Error:Step failed
java.lang.NullPointerException: Cannot invoke "org.openqa.selenium.devtools.DevTools.createSession()" because "this.devTools" is null

[globalworming]

you are just declaring Devtools devtools;, they are just null. you have to get devtools from the webdriver like here

though in step libraries you don't get the webdriver, do you?

hi @globalworming,
I have the same result running tests on docker-selenium 4.5.0-20221004 version.
Browser: chrome
Serenity-core: 3.3.4 version

BrowseTheWeb.as(actor).getDevTools() is returned null.

getDevTools() will return null if the driver does not support the HasDevTools interface - are you sure the driver you are using supports dev tools?

Hi @wakaleo,
It doesn't work on serenity core 3.3.4,3.3.5, but works on 3.2.5
Our configuration is:

• setup selenium hub and node with Chrome and pass parameters
  -Dwebdriver.remote.url=http://localhost:4444/wd/hub
  -Dwebdriver.driver=chrome

Works when run on local driver for all versions
-Dwebdriver.chrome.driver=/home/user/Downloads/chromedriver

Cool, so this can be closed?

[oleksandr-kobzan-philips]

please don't close it because the issue with RemoteWebDriver still exists.

[wakaleo]

This isn't a Serenity issue. The RemoteWebDriver class does not implement the HasDevTools interface, and so cannot provide a DevTools object. The DevTools support works correctly for drivers that implement HasDevTools, e.g.

        BrowseTheWeb.as(actor).maybeGetDevTools().ifPresent(
                devTools -> {
                    devTools.createSession();
                    devTools.send(Log.enable());
                    devTools.addListener(Log.entryAdded(), logEntry -> {
                        System.out.printf("DEVTOOLS LOG: %s\n - %s: %s",logEntry.getLevel(), logEntry.getUrl(), logEntry.getText());
                    });
                }
        );
