##Problem When Karate runs Chrome driver in headless mode (in the pipeline) you might see the error:

driver config / start failed: chrome server returned empty list from http://localhost:9222, options: {type=chrome, headless=true, target=null}

##Analyse This might because Chrome has been updated and there was a change that impacted the headless mode.

##Solution In the Karateconfig.js change the way the option to run in headless mode using switch on, here is a example:

karate.configure('driver', { type: 'chrome', executable: 'C://Program Files//Google//Chrome//Application//chrome.exe', addOptions: [runHeadless, '--enable-automation']});

##More information This is caused by a change in Chrome: more information about this issue can be found here

##Problem When Karate starts Chrome, a window is opened but nothing happens. The log shows the error:

Invalid handshake response getStatus: 403 Forbidden

##Analyse This might because Chrome has been updated and there was a change that impacted test automation capabilities of the browser.

##Solution In the Karateconfig.js add the option to run automation and allow remote origins. For example:

driver_configuration: { headles: headless, executable: chromeExecutable, addOptions: ['--enable-automation', "--remote-allow-origins=*"]}

##More information Open Chrome windows might not close at the end of the test. More investigation is needed to see why this happens.

##Problem When running karate 1.4 and you save cookies from the login script, the domain will not be automatically saved

##Solution Set it manually, after saving the cookies :

  * karate.write('{"n_at":"' + accessToken + '", "idsBaseUrl":"' + identityServerUrl + '", "timestamp": ' + timestamp + ', "idsrv":' + idsrv + ', "idsrvSession": ' + idsrvSession + '}', '/testdata/n_at.json')

  # add domain to idsrv cookie, needed for karate 1.4:
  * def authJson = read('file:target/testdata/n_at.json')
  * set authJson.idsrv.domain = identityServerUrl.slice(8)
  * set authJson.idsrvSession.domain = identityServerUrl.slice(8)
  * karate.write(authJson,'testdata/n_at.json')
