How to fix behat 'DMore\ChromeDriver\StreamReadException' in behat script

Question

I am executing my behat script and getting the following exception :

DMore\ChromeDriver\StreamReadException in /vendor/dmore/chrome-mink-driver/src/DevToolsConnection.php

I am getting the following exception in my local and also in my Acquia pipeline.Strange thing is that this exception does not appears everytime and appears on different step definations each time.

Feature: Test SEARCH box
  @javascript @api @errors
  Scenario: Test For the SEARCH box                                                                                     
    Given I am on "/"
                                                                                                   # Drupal\DrupalExtension\Context\MinkContext::visit()
DMore\ChromeDriver\StreamReadException in /<project_folder>/vendor/dmore/chrome-mink-driver/src/DevToolsConnection.php

Still have not found a solution. I have noticed that when I am running a headless chrome browser and am using the chrome debug tools things like "clicking" a button will cause this error every time. — Jeff Mattson, Dec 16 '19 at 18:51

This solution worked for me . In your code wherever 'socket_timeout' is being used just increase the time

In my configuration file

local.yml

sessions:
        default:
          chrome:
            # Set the optimal Socket Timeout to avoid client-server connection problems in behat scripts.
            socket_timeout: 60
