TypeError: c is undefined -> Trying to call getText() of a WebElement instance #2050

Testcase

Trying to call getText() of a WebElement instance returned by a @FindBy tag

public class ApiDetalleBibliograficoPage
{
    @FindBy(tagName = "accessRestriction")
    List<WebElement> accessRestrictionElements;

    public List<WebElement> getAccessRestrictionElements()
    {
        return this.accessRestrictionElements;
    }
}

...
    @BeforeClass
    public static void setUpBeforeClass()
        throws Exception
    {
...
        detallePage = PageFactory.initElements(driver, ApiDetalleBibliograficoPage.class);
    }
...
    @Test
    public void test01DetalleId()
        throws Exception
    {
...
        detallePage.getAccessRestrictionElements().get(0).getText().trim()); // Throws an error
    }

I verified that the page had a valid XML document that contains the node and contains some text :

<?xml version="1.0" encoding="UTF-8"?>

Trace-level log

Here it's the trace level log Trace-level log.txt

whimboo commented 1 year ago

Could you please attach a trace-level log from geckodriver? Also a minimized HTML testcase would be great to have. Right now it's not clear if this comes from geckodriver or your in use Selenium binding.

I uploaded the trace level log.

I put the exact XML (yes, XML, not HTML) that the server responds on the issue.

PD: I know that using Selenium to run tests against a XML it's odd (I didn't create this tests). But this tests have many years, and had been working fine a lot of time. Only we begin to get this error a few days ago with the last automate update of Firefox

Thanks. The trace log revealed some information:

atom ... mmandsChild.jsm:335:22\nreceiveMessage@chrome://remote/content/marionette/actors/MarionetteCommandsChild.jsm:121:31\n"},null]
1665120483225   webdriver::server       DEBUG   <- 500 Internal Server Error {"value":{"error":"unknown error","message":"TypeError: c is undefined","stacktrace":"$b@chrome://remote/content/marionette/atom.js:85:50\nX@chrome://remote/content/marionette/atom.js:83:252\njc@chrome://remote/content/marionette/atom.js:96:68\noc@chrome://remote/content/marionette/atom.js:101:95\natom.getElementText/</<@chrome://remote/content/marionette/atom.js:104:295\natom.getElementText/<@chrome://remote/content/marionette/atom.js:104:481\natom.getElementText@chrome://remote/content/marionette/atom.js:104:505\ngetElementText@chrome://remote/content/marionette/actors/MarionetteCommandsChild.jsm:335:22\nreceiveMessage@chrome://remote/content/marionette/actors/MarionetteCommandsChild.jsm:121:31\n"}}

So the underlying problem is the call into the Selenium atoms when using getText().

Also thanks a lot for the XML testcase. I can reproduce this locally now with using Marionette directly. I filed https://bugzilla.mozilla.org/show_bug.cgi?id=1794099 to handle this particular issue.

@Zardoz89 please note that as long this isn't fixed you can set the following Firefox preference and the test should pass: layout.css.computed-style.styles-outside-flat-tree=true.

whimboo commented 1 year ago

Again, thanks for your help. The fix landed and should be available in the most recent Firefox 108 nightly build.
