Php-webdriver: "Unable to create new create new session"

[asofan]

What are you trying to achieve? (Expected behavior)

The environment I am running is Windows Server 2008 R2 with IIS 7

I am trying to follow the instructions on the Readme.md file:
https://github.com/facebook/php-webdriver/blob/community/README.md

What do you get instead? (Actual behavior)

"Unable to refresh session list."

and

"Unable to create new session"

How could the issue be reproduced? (Steps to reproduce)

I ran the Selenium server using this method:

CMD > Run-as Administrator

_java -jar selenium-server-standalone-3.5.0.jar_

The result from the command is:

_14:56:56.648 INFO - Selenium build info: version: '3.5.0', revision: '8def36e068'

14:56:56.960 INFO - Selenium Server is up and running_

So I assume everything is running OK. However, when I try to run the http://localhost/example.php file after following the steps in the readme file, I get this error on the browser:

"This page isn’t working
localhost is currently unable to handle this request.
HTTP ERROR 500"

to troubleshoot, I tried to go to the url: http://localhost:4444/wd/hub/

and at the top of the page I saw a red alert saying

"Unable to refresh session list."

the resulting log from the command prompt:

When I click to create a session, no matter which browser I select, I get "

"Unable to create new session"

the resulting log is:

Hi @asofan,
this error:

to troubleshoot, I tried to go to the url: http://localhost:4444/wd/hub/
and at the top of the page I saw a red alert saying
"Unable to refresh session list."

has been solved here:
https://github.com/SeleniumHQ/selenium/issues/4496
and was included in the Selenium 3.5.2 release.

I can't say if it'll help with your issue.

[OndraM]

I guess it may be related. @asofan could you please try with latest Selenium server whether the problem still persist? If so, I would reopen the issue then.

Also please provide the exact source code you use to run the PHP test to help us debug the issue :).

Thanks!

Hey, I had the same issue with chrome/firefox55.0.3(latest) browser and standalone-selenium.
Tried standalone versions 3.0.0, 3.0.1, 3.0.2, 3.0.4, 3.5.2.

I thought the standalone jar incorporated the gecko driver (for firefox) but I was wrong.
Hence, I downloaded the driver (latest), added it to environment variables and it was fixed.

Hope it could help you, best wishes.

I can confirm that the issue of "Unable to refresh session list" is solved.

However, still getting the "Unable to create new session" error

this is the example.php file is the one included and can be found here:

https://github.com/facebook/php-webdriver/blob/community/example.php

the result when running http://127.0.0.1/example.php is this:

=============================================

You were right fllprbt. I downloaded the browser driver and it now works. Thank you.

[lisitso]

I have the same issue while executing example.php:

PHP Fatal error:  Uncaught Facebook\WebDriver\Exception\SessionNotCreatedException: Unable to create new service: GeckoDriverService

any help will be appreciated

after adding the Gecko driver the example.php works perfect when running on the localhost on the IIS server.

so, http://localhost/example.php works perfect

However, when I moved it to another site on the same IIS server, I get a class not found error.

So, when I run it on http://www.mysite.com/example.php

_the file is located here: C:\inetpub\wwwroot\example.php_

I get this error:

Fatal error: Class 'Facebook\WebDriver\Remote\DesiredCapabilities' not found in C:\HostingSpaces\mysite.com\mysite.com\wwwroot\example.php on line 13

the file is located here:
_C:\HostingSpaces\mysite.com\mysite.com\wwwroot\example.php_

Can you help?

Thanks in advance

You are getting out of topic, please don't continue here. Your problem may be related to missing composer or priviliges or other things.

Best wishes,
