php Codeception not-so-quick start: [PHPUnit\Framework\Exception] Undefined index: ELEMENT

So, I followed the Codeception Quick Start instructions faithfully. I run the first example test using the PhpBrowser...

# Codeception Test Suite Configuration
#
# [further comments omitted]
# 
actor: AcceptanceTester
modules:
    enabled:
        - PhpBrowser:
            url: 'http://office.localhost/'
            browser: 'firefox'
        - \Helper\Acceptance

and the test:

<?php

class FirstCest
{               
    public function frontpageWorks(AcceptanceTester $I)
    {
        $I->amOnPage('/');
        $I->see('We hope you enjoy it');

    }
}

and all is well.

Then I change the configuration to this:

actor: AcceptanceTester
modules:
    enabled:
        - WebDriver:
            url: 'http://office.localhost/'
            browser: 'firefox'
        - \Helper\Acceptance

per the instructions, and I have Selenium installed and up and running, and away we go...

1) FirstCest: Frontpage works
 Test  tests/acceptance/FirstCest.php:frontpageWorks

  [PHPUnit\Framework\Exception] Undefined index: ELEMENT  


Scenario Steps:

 2. $I->see("InterpretersOffice") at tests/acceptance/FirstCest.php:22
 1. $I->amOnPage("/") at tests/acceptance/FirstCest.php:21

#1  /opt/www/court-interpreters-office/vendor/facebook/webdriver/lib/Remote/RemoteWebDriver.php:198
#2  Codeception\Module\WebDriver->see
#3  /opt/www/court-interpreters-office/tests/_support/_generated/AcceptanceTesterActions.php:363
#4  /opt/www/court-interpreters-office/tests/acceptance/FirstCest.php:22
#5  FirstCest->frontpageWorks

Selenium is driving Firefox, the page is loaded, the content that $I want to see() is there, so that ain't the problem. I have poked around in the source a bit, but haven't figured this out. I have tried changing $I->see() to $I->seeInSource() and found that does work, FWIW.

Any thoughts?

There are different situations on my Ubuntu ver. 18.x:

  1. The vendor files has been for years, I have to rm the vendor fold and rebuild it with php composer.phar require facebook/webdriver for my PHP library.

  2. The version of selenium-server-standalone-x.jar and chromedriver doesn't match. So download more version and try, finally you will get one pair to work.

In my case the only solution was:

Install chromedriver in a path that is in $PATH (/usr/bin or /bin)

and using in your test class:

$capabilities = DesiredCapabilities::chrome()

It works with executing Selenium standard way:

 java -jar selenium-server-standalone-3.14.0.jar

The problem is apparently that Facebook's php-webdriver isn't compatible with current Firefox.

These threads discuss the issue in more detail, and php-webdriver issue #469 tracks adding full W3C WebDriver support (which will fix the incompatibility).

A workaround is to add the -enablePassthrough false argument when launching Selenium. For example:

java -Dwebdriver.gecko.driver=./geckodriver -jar selenium-server-standalone-3.8.1.jar -enablePassThrough false

Unfortunately, Selenium removed support for pass through mode in 3.9, so you'll have to use an older version.

Another workaround is to switch to Chrome.
