When trying to run Selenium on Windows 10 Edge Chrome version 80, I am getting the following error:

Z:\node_modules\selenium-webdriver\lib\promise.js:2626
        throw error;
        ^

WebDriverError: Unknown error
    at parseHttpResponse (Z:\node_modules\selenium-webdriver\lib\http.js:536:11)
    at Z:\node_modules\selenium-webdriver\lib\http.js:441:30
    at processTicksAndRejections (internal/process/task_queues.js:97:5)
From: Task: WebDriver.createSession()
[...]

I am building it like this:

const webdriver = require('selenium-webdriver'),
    edge = require('selenium-webdriver/edge');

 var service = new edge.ServiceBuilder()
     .setPort(55555)
     .build();

 var options = new edge.Options();
 driver = edge.Driver.createSession(options, service);

Does anyone see why this might be happening? Has anyone had success building the driver using the javascript bindings and can share how they were able to do that?

I'm confident that I have the correct version of the Microsoft Edge Driver UPDATE: Also note that Edge launches, but never begins navigating. The script works fine for all other browsers.

Possible relevant note: I'm running in a VirtualBox VM of Windows 10, but the automation scripts all live on the Z: on my Mac. I have added the z: to my path.

MicrosoftwebDriver is running, too: Running, too

  • Edge launches, so i am convinced I have the right driver. I'll recheck the path.

Verify that driver is in PATH:

just open cmd and type the driver name,

enter image description here

This is the tested code for Edge legacy:

const {Builder, By, Key, until} = require('selenium-webdriver');

(async function example() {
  let driver = await new Builder().forBrowser('MicrosoftEdge').build();
  try {
    await driver.get('http://www.google.com/ncr');
    await driver.findElement(By.name('q')).sendKeys('webdriver', Key.RETURN);
    await driver.wait(until.titleIs('webdriver - Google Search'), 1000);
  } finally {
    await driver.quit();
  }
})();

Note: I have the webdriver in the path, so if C:/tmp/MicrosoftWebDriver.exe is the path of your webdriver then add c:/tmp/ to path

I checked your code even thats working:

const {Builder, By, Key, until} = require('selenium-webdriver');

const webdriver = require('selenium-webdriver'),
    edge = require('selenium-webdriver/edge');

 var service = new edge.ServiceBuilder()
     .setPort(55555)
     .build();

 var options = new edge.Options();
 driver = edge.Driver.createSession(options, service);

(async function a(){


    await driver.get('http://www.google.com/ncr');
    await driver.findElement(By.name('q')).sendKeys('webdriver');
    await driver.wait(until.titleIs('webdriver - Google Search'), 1000);
    await driver.quit();
})()

Finally got it to work.

/* In another command prompt window enter the command:
   msedgedriver.exe --verbose  

   Then run the script as normal in the other command prompt
*/
const Selenium = require("selenium-webdriver");
const BROWSER_NAME = Selenium.Browser.EDGE;
const builder = new Selenium.Builder().forBrowser(BROWSER_NAME)
.withCapabilities({
        "browserName": 'MicrosoftEdge',
        "browserVersion": '81.0',
        "platformName": 'Windows 10',
        'ms:edgeChromium': true
    }).usingServer('http://localhost:9515')

const driver = builder.build()
