I am running a Docker-based PowerShell Universal (PSU) environment on a Linux image and trying to automate tasks using the Selenium module. Despite successfully installing the module, I am facing several issues when creating Selenium objects such as ChromeOptions or starting browsers like Chrome and Firefox.

Environment Details:

• OS: Linux (Docker container)
• PowerShell Version: 7.3.9
• Selenium Module Version: 3.0.1 (Installed from PSGallery)

What I Did:

1. Installed Selenium Module:

   Install-Module -Name Selenium -Force
   Import-Module Selenium
   Get-InstalledModule -Name Selenium
   

   Result: Successfully installed and imported the module.

2. Verified WebDriver Binaries:

   which chromedriver
   which google-chrome
   which firefox
   which geckodriver
   

   Result: All binaries are located in /usr/bin/ and are executable.

3. Set Up Xvfb (Headless Server):

   Xvfb :99 -screen 0 1920x1080x24 &
   export DISPLAY=:99
   

   Error: Fatal server error: Server is already active for display 99.

   Fix Attempt: Removed the lock file and retried:

   rm -f /tmp/.X99-lock
   Xvfb :99 -screen 0 1920x1080x24 &
   export DISPLAY=:99
   

   Result: Process started without errors after removing the lock file.

4. Attempted to Create Chrome Options in PowerShell:

   $ChromeOptions = New-Object OpenQA.Selenium.Chrome.ChromeOptions
   $ChromeOptions.AddArgument("--headless")
   $ChromeOptions.AddArgument("--no-sandbox")
   $ChromeOptions.AddArgument("--disable-dev-shm-usage")
   $ChromeOptions.AddArgument("--disable-gpu")
   

   Error: New-Object: Cannot find type [OpenQA.Selenium.Chrome.ChromeOptions]: verify that the assembly containing this type is loaded.

5. Attempted to Start Chrome in Headless Mode:

   $Driver = Start-SeChrome -ChromeOptions $ChromeOptions
   

   Error: Start-SeChrome: A parameter cannot be found that matches parameter name 'ChromeOptions'.

6. Tried Manually Loading DLLs:

   Add-Type -Path "/root/Selenium/Selenium/WebDriver.dll"
   Add-Type -Path "/root/Selenium/Selenium/WebDriver.Support.dll"
   

   Error: Add-Type: Cannot bind parameter 'Path' to the target. Exception setting 'Path': Cannot find path...

7. Checked Selenium Module Path:

   $Module = Get-Module Selenium
   $ModulePath = $Module.ModuleBase
   

   Result: Selenium module path is correctly retrieved.

8. Tried Launching Firefox:

   $FirefoxOptions = New-Object OpenQA.Selenium.Firefox.FirefoxOptions
   $FirefoxOptions.BrowserExecutableLocation = "/usr/bin/firefox"
   $Driver = Start-SeFirefox -FirefoxOptions $FirefoxOptions
   

   Error: New-Object: Cannot find type [OpenQA.Selenium.Firefox.FirefoxOptions]: verify that the assembly containing this type is loaded.

Summary of Errors Encountered:

• Cannot find type [OpenQA.Selenium.Chrome.ChromeOptions] in PowerShell.
• Start-SeChrome: A parameter cannot be found that matches parameter name 'ChromeOptions'.
• Cannot find path '/root/Selenium/Selenium/WebDriver.dll' when manually loading DLLs.
• Issues with running Xvfb due to an active display server lock.

Can someone help me fix this issue ?
