Steps to reproduce -

This is being run from the unit test but all it is testing is whether or not an element is displayed and then entering a string of text, the username, into the field (How hard is that?). The chrome tests run just fine on the same page (hmmmmm):

• System.InvalidOperationException : Expected [object Undefined] undefined to be a string (IndexOutOfBounds)
  at OpenQA.Selenium.Remote.RemoteWebDriver.UnpackAndThrowOnError(Response errorResponse)
  at OpenQA.Selenium.Remote.RemoteWebDriver.Execute(String driverCommandToExecute, Dictionary`2 parameters)
  at OpenQA.Selenium.Remote.RemoteWebElement.SendKeys(String text)
  at DPEXSelenium.Firefox_Tests.DpexLoginFirefox.ProcessLogin(String username, String password) in C:\MyProjects\Sandbox\DPEXSelenium\DPEXSelenium\Firefox Tests\DPEXLoginFirefox.cs:line 90

Given I have an open Firefox browser
-> done: DPEXLoginFirefoxSteps.GivenIHaveAnOpenBrowser() (8.8s)
And The page has loaded in Firefox
-> error: Expected [object Undefined] undefined to be a string (IndexOutOfBounds)
When I login to the site in Firefox
-> skipped because of previous errors
Then the result in FireFox should be true
-> skipped because of previous errors

I can’t parse what this issue is about. Sorry.

[alvladimirov]

Having same problem with Firefox v53. Downgrading back to v52 solved the problem.
Gecko Driver version: v0.15.0

CODE that triggers this - a SendKeys() call:

[FindsBy(How = How.Id, Using = "Eligibility_DOBDay")] 
private IWebElement Eligibility_DoB_Day;
<....>
Eligibility_DoB_Day.SendKeys(p.ToString());

ELEMENT I'm trying to interact with:
<input class="xxshort numeric_dayofmonth" data-val="true" data-val-number="The field DOBDay must be a number." id="Eligibility_DOBDay" maxlength="2" name="Eligibility.DOBDay" pattern="[0-9]*" value="" autocomplete="off" type="text">

EXCEPTION:
Execute
System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.InvalidOperationException: Expected [object Undefined] undefined to be a string (IndexOutOfBounds)

If this is about send keys not working (I can’t really guess without a trace-level log!), then it is broken with the latest Firefox Nightly and geckodriver 0.15.0. Upgrading to 0.16.0 when it comes out should solve any incompatibilities between Nightly and geckodriver.

I don’t know what the issue is about Firefox 53 though.

[MatejQ]

Just got the same issue after freshly upgrading Firefox to version 53. On version 52, tests were running fine. The error seems to be triggered by SendKeys() call in Selenium, which is necessary to pass the login page.

[kaspmode]

Me to same issue SendKeys() generates error, besides go back to the older version does anybody has a solution? :(

[andreastt]

The send keys problems have already been reported in #659, and been fixed.

[whimboo]

Well, we should note that geckodriver 0.16 would be required which hasn't been released yet.

[whimboo]

Can someone please verify with https://github.com/mozilla/geckodriver/releases/tag/v0.16.1? Thanks.

[alvladimirov]

Works perfectly fine for me.
GeckoDriver : 0.16.1 (32bit)
Selenium: 3.4.0
Firefox: v53

I checked with exactly the same code that used to fail on SendKeys ().
Thank you for the prompt fix!

[adeelilyas]

Just update GeckoDriver to the latest with Firefox v53 and it will work. Download the one you required from here.
