[🐛 Bug]: Unable to upload file to a Mac Safari node when using selenium Grid.

[vvbisht]

What happened?

Selenium version : 4.24.0
Java : 11
Platform : MAC Sonoma 14.0
Browser : Safari v 17

I have setup a Selenium Grid with a MAC hub and multiple mac nodes. When i am trying to perform a file upload operation through grid it's failing and throwing following exception.
org.openqa.selenium.InvalidArgumentException: An invalid command argument was specified: One or more files could not be selected.

Please note that on running the test without grid this seems to be working fine. I have tried changing the path with "/" and "\" but nothing seems to be working.

How can we reproduce the issue?

String hub = "http://*.*.*.*:4444/wd/hub";
            SafariOptions options = new SafariOptions();
            options.setCapability("browserName", "safari");
            options.setCapability("platformName", "mac");
            WebDriver driver = null;
            //driver = new RemoteWebDriver(new URL(hub), options);
            RemoteWebDriver driver = new RemoteWebDriver(new URL(hub), options);
            driver.setFileDetector(new LocalFileDetector());
        String filePath = "C:/sample.txt";
        driver.get("https://the-internet.herokuapp.com/upload");
        WebElement element = driver1.findElement(By.id("file-upload"));
        element.sendKeys(filePath);

Hi, @vvbisht.
Please follow the issue template, we need more information to reproduce the issue.

Either a complete code snippet and URL/HTML (if more than one file is needed, provide a GitHub repo and instructions to run the code), the specific versions used, or a more detailed description to help us understand the issue.

Note: If you cannot share your code and URL/HTML, any complete code snippet and URL/HTML that reproduces the issue is good enough.

Reply to this issue when all information is provided, thank you.

I tried to reproduce it locally but I was not able to. My local OS is MacOS and I created a Hub and 2 Nodes. The code shared worked as expected with a minor tweak to point to the correct driver variable.
This is the code snippet:

  public class SafariGridFileUpload {
  public static void main(String[] args) throws MalformedURLException {
    String hub = "http://localhost:4444";
    SafariOptions options = new SafariOptions();
    RemoteWebDriver driver = new RemoteWebDriver(new URL(hub), options, false);
    driver.setFileDetector(new LocalFileDetector());
    String filePath = "/Users/puja/Downloads/profile_photo.jpeg";
    driver.get("https://the-internet.herokuapp.com/upload");
    WebElement element = driver.findElement(By.id("file-upload"));
    element.sendKeys(filePath);
  }
}

From the logs shared, I observe that the OS is Windows System info: os.name: 'Windows 11'. Also, the path passed is Windows file system path. For a MAC Hub, it needs to be MAC based path. Please share your setup of the Grid so we can understand this better.

If you are using a virtual machine, then you might need to add files to the virtual machine and accordingly set the path and upload it.

Here's how we can configured our setup.

1. There's a windows VM which will execute the tests which are triggered using a Jenkins job.
2. There are separate hub/nodes created for Linux, Windows and MAC.
3. Windows VM sends the command to respective hub which is then propagated to nodes.

In Windows and Linux setup same code works just fine, but only in MAC it's failing.
The code that i have shared is just an eg. in our framework we are using "user.dir" property to fetch the path of the file.

[vvbisht]

If you are using a virtual machine, then you might need to add files to the virtual machine and accordingly set the path and upload it.

Will it not work with LocalFileDetector, is it required to place the files in all the nodes? It works well in Windows and Linux.

Thank you for sharing the details! I understand this better. However, I cannot reproduce the same setup locally, considering there are so many pieces and I don't have access to a Windows machine. As far as I understand, the issue is the path for MacOS in the shared code. A MAC Grid does not understand the path pass since it is not a MAC OS path. So you will need to fix that bit to solve the problem. The LocalFileDetector tries to detect the file on the local disk.
I am closing the issue since this is not a Selenium problem. But feel free to discuss this further and get help from the community in our Slack channel.
