Existing connection was forcibly closed by the remote host

vishvambruth.javagal · October 25, 2022, 8:09am

Hi Team,

I have the below code which is working fine in headless mode till clicking on the CONFIGURATION link. But once I click on the CONFIGURATION link I would like to.

Select ‘Server Template’

Enter ‘Discovery Document URL’

Click on ‘Save’

Could you please help on the same.

import { chromium } from 'k6/x/browser';
import { options, openidconnect_url, discovery_document_url, userName, password } from "./common_openid.js";
export {options};

export default function () {
  const browser = chromium.launch({
    headless: true,
    slowMo: '1s',
  });
  const context = browser.newContext();
  const page = context.newPage();

  // 01. Go to the openidconnect landing page and click on CONFIGURATION
  page.goto('https://openidconnect.net/', { waitUntil: 'networkidle' }).then(() => {    
    page.screenshot({ path: 'screenshots/01_screenshot.png' });
    page.waitForSelector('button[class="playground-header-config btn btn-link"]');        
    return page.click('button[class="playground-header-config btn btn-link"]');
  }).then(() => {    
    page.screenshot({ path: 'screenshots/02_screenshot.png' });
    page.selectOption("select[name='server']", "Custom");
    page.type("input[placeholder='https://my-oidc.com/.well-known/openid-configuration']", "some test url");
    page.click('button[class="code-box-btn is-alt"]');
    page.screenshot({ path: 'screenshots/03_screenshot.png' });
  }).finally(() => {
    page.close();
    browser.close();
  });
}

Hi @vishvambruth.javagal,

Since the click action returns a promise, we should wait for it to return (like below):

  page.goto('https://openidconnect.net/', { waitUntil: 'networkidle' }).then(() => {    
    ...
  }).then(() => {    
    ...
    page.type("input[placeholder='https://my-oidc.com/.well-known/openid-configuration']", "some test url");
    return page.click('button[class="code-box-btn is-alt"]'); // <-- this
  }).then(() => {                                             // <-- this
    page.screenshot({ path: 'screenshots/03_screenshot.png' });
  }).finally(() => {
    page.close();
    browser.close();
  });

I tried this, and it took three screenshots.

vishvambruth.javagal · October 25, 2022, 9:37am

But its not selecting the value from dropdown and typing the required text in the text box.

Any thing wrong with the below code:

page.selectOption("select[name='server']", "Custom");
page.type("input[placeholder='https://my-oidc.com/.well-known/openid-configuration']", "some test url");
page.click('button[class="code-box-btn is-alt"]');
page.screenshot({ path: 'screenshots/03_screenshot.png' });

inancgumus · October 25, 2022, 9:54am

The click action returns a promise (as I explained above), the last code you shared doesn’t handle that, but the last one I shared does.

Besides that, the value in the dropdown is "custom" (with a lowercase c, not Custom). Please change the selectOption as below:

page.selectOption("select[name='server']", "custom");

And please don’t forget handling the promise as I explained in my previous comments.

vishvambruth.javagal · October 25, 2022, 2:05pm

Hi @inanc,

Thanks, I have written the below script and now its selecting the dropdown value. But after selecting the dropdown value Im trying to set the ‘Discovery Document URL’ with some URL and its failing to type in. Could you please take a look.

Note: The issue persists when we try to type long URL. Typing short URLs is working fine.
Unable to type: https://my-oidc.com/.well-known/openid-configuration
Able to type: https://my-oidc.com/

import { chromium } from 'k6/x/browser';

export default function () {
  const browser = chromium.launch({
    headless: true,
    slowMo: '1s',
  });
  const context = browser.newContext();
  const page = context.newPage();

  // 01. Go to the openidconnect landing page and click on CONFIGURATION
  page.goto('https://openidconnect.net/', { waitUntil: 'networkidle' }).then(() => {    
    page.screenshot({ path: 'screenshots/01_screenshot.png' });
    page.waitForSelector('button[class="playground-header-config btn btn-link"]');        
    return page.click('button[class="playground-header-config btn btn-link"]');
  }).then(() => {    
    page.screenshot({ path: 'screenshots/02_screenshot.png' });   
    page.waitForSelector("select[name='server']"); 
    return page.selectOption("select[name='server']", "custom");
  }).then(() => {    
    page.screenshot({ path: 'screenshots/03_screenshot.png' });
    page.waitForSelector("input[placeholder='https://my-oidc.com/.well-known/openid-configuration']");     
    return page.click("input[placeholder='https://my-oidc.com/.well-known/openid-configuration']");   
  }).then(() => {   
    page.screenshot({ path: 'screenshots/04_screenshot.png' }); 
    page.type("input[placeholder='https://my-oidc.com/.well-known/openid-configuration']", 'https://my-oidc.com/.well-known/openid-configuration');
    page.screenshot({ path: 'screenshots/05_screenshot.png' });
  }).finally(() => {
    page.close();
    browser.close();

Hi @vishvambruth.javagal,

I tried a slightly modified script on my Mac, and it took 5 screenshots. The selectOption action does not return a promise. The modified script looks as the following:

import { chromium } from 'k6/x/browser';

export default function () {
  const browser = chromium.launch({
    headless: true,
    slowMo: '1s',
  });
  const context = browser.newContext();
  const page = context.newPage();

  // 01. Go to the openidconnect landing page and click on CONFIGURATION
  page.goto('https://openidconnect.net/', { waitUntil: 'networkidle' }).then(() => {    
    page.screenshot({ path: 'screenshots/01_screenshot.png' });
    page.waitForSelector('button[class="playground-header-config btn btn-link"]');        
    return page.click('button[class="playground-header-config btn btn-link"]');
  }).then(() => {    
    page.screenshot({ path: 'screenshots/02_screenshot.png' });   
    page.waitForSelector("select[name='server']"); 
    page.selectOption("select[name='server']", "custom"); // <-------------------
    page.screenshot({ path: 'screenshots/03_screenshot.png' });
    page.waitForSelector("input[placeholder='https://my-oidc.com/.well-known/openid-configuration']");     
    return page.click("input[placeholder='https://my-oidc.com/.well-known/openid-configuration']");   
  }).then(() => {   
    page.screenshot({ path: 'screenshots/04_screenshot.png' }); 
    page.type("input[placeholder='https://my-oidc.com/.well-known/openid-configuration']", 'https://my-oidc.com/.well-known/openid-configuration');
    page.screenshot({ path: 'screenshots/05_screenshot.png' });
  }).finally(() => {
    page.close();
    browser.close();
  });
}

That’s interesting. By the way, you don’t have to click on the input box (The type action already does that). So run with the following script:

import { chromium } from 'k6/x/browser';

export default function () {
  const browser = chromium.launch({
    headless: true,
    slowMo: '1s',
  });
  const context = browser.newContext();
  const page = context.newPage();

  // 01. Go to the openidconnect landing page and click on CONFIGURATION
  page.goto('https://openidconnect.net/', { waitUntil: 'networkidle' }).then(() => {    
    page.screenshot({ path: 'screenshots/01_screenshot.png' });
    page.waitForSelector('button[class="playground-header-config btn btn-link"]');        
    return page.click('button[class="playground-header-config btn btn-link"]');
  }).then(() => {    
    page.screenshot({ path: 'screenshots/02_screenshot.png' });   
    page.waitForSelector("select[name='server']"); 
    page.selectOption("select[name='server']", "custom");
    page.screenshot({ path: 'screenshots/03_screenshot.png' });
    page.type("input[placeholder='https://my-oidc.com/.well-known/openid-configuration']", 'https://my-oidc.com/.well-known/openid-configuration');
    page.screenshot({ path: 'screenshots/04_screenshot.png' });
  }).finally(() => {
    page.close();
    browser.close();
  });
}

Could you run the script above with the following command and send us the debug log?

Is this the full debug log?

vishvambruth.javagal · October 27, 2022, 1:40pm

@inanc. No its not allowing to paste the full log here there is a limit. Is there any way I can extract the logs to a file and send?

inancgumus · October 27, 2022, 3:08pm

I suggest this one.

vishvambruth.javagal · October 27, 2022, 3:39pm

Here also I’m not able to paste the entire log the size too big. You can run this in any windows machine and see you will be able to reproduce this issue.

inancgumus · October 27, 2022, 4:04pm

Unfortunately, I don’t have a Windows machine. I’ll see what I can do. We can tackle this problem if you don’t mind opening an issue on our Github. Please don’t forget to link to this post. Thanks!

Thank you! We’ll consider it in the next planning session (next week or so).

Arjun · November 2, 2022, 1:57pm

@inanc : I am Facing same issue, we can consider this one Blocker for windows machines. Seems this issue happening due to wait mechanism. While pages are taking longer time for loading, K6 is not waiting for page load, Sometimes DOM got loaded but not actual UI. in that kind of scenarios it forcibly closing the session.

I did tried using below wait Options.

page.waitForLoadState(‘networkidle’);
sleep(15);
sleep(Math.random() * 15);
page.waitForNavigation({ timeout: 100000 });

None of the above methods wait specified until the page get loaded.

Ex : My application will take >=60< seconds to load dashboard page. i tried all the above wait methods for interacting next element after Navigating to dashboard. Obsrved K6 trying to interact element very fast. but all the cases it will not work. then in windows machines we are getting “ERRO[0042] communicating with browser: read tcp 127.0.1.0.1:25484->127.0.1.0.1:25484: wsarecv: An existing connection was forcibly closed by the remote host. category=cdp elapsed=“0 ms” goroutine=88”

Hi @Arjun,

I’ll take another look at this issue soon. Can you please give us the following details to help you further:

The OS and version your computer is running. (10 or 11, WSL/WSL2 or powershell).
Which version of xk6-browser (was it from the release page, or did you build it yourself?).
The full script (pointing to a public website).
The log output.

Cheers,
Ankur

vishvambruth.javagal · November 7, 2022, 7:38pm

@inanc @ankur You have any update on this issue?

inancgumus · November 8, 2022, 9:28am

Hi @vishvambruth.javagal,

You can track our progress from the issue you opened.

Thanks.
