selenium: [🐛 Bug]: SelectElement not working after updating selenium webdriver 4 and IEDriverServer 4

What happened?

after updating selenium WebDriver (3.15 to 4.0.0) and IEDriver (3.150.1 to 4.0.0) getting below error while setting dropdown value, code was working properly with old selenium version (3): Error : Cannot click on option element. Executing JavaScript click function returned an unexpected error, but no error could be returned from Internet Explorer’s JavaScript engine

HTML :

<SELECT id=selCountry"> <OPTION selected value=0>None</OPTION> <OPTION value=1>India</OPTION></SELECT>

C# code : public By countrySelector = By.Id(“selCountry”); public string Country { set => new SelectElement(Driver.FindElement(countrySelector )).SelectByText(value); }

   Country= "India";

How can we reproduce the issue?

HTML : 
<TD vAlign=top><SELECT id=selCountry">
<OPTION selected value=0>None</OPTION> <OPTION value=1>India</OPTION></SELECT>
</TD>
       

 public By countrySelector = By.Id("selCountry");

        public string Country
        {
            set => new SelectElement(Driver.FindElement(countrySelector )).SelectByText(value);
        }

Country= "India";

I found a solution! Use JavaScriptExecutor.

Selenium Webdriver version : 4.1.3 IEDriver version : 4.0.0

 public void selectOption(WebDriver wdriver,WebElement wele,String value) throws Exception {
      JavascriptExecutor jexec = (JavascriptExecutor) wdriver;
      jexec.executeScript("var select = arguments[0]; for(var i = 0; i < select.options.length; i++){ if(select.options[i].text == arguments[1]){ select.options[i].selected = true; } }", wele, value);
  }

  public void deselectOption(WebDriver wdriver,WebElement wele) throws Exception {
      JavascriptExecutor jexec = (JavascriptExecutor) wdriver;
      jexec.executeScript("var select = arguments[0]; for(var i = 0; i < select.options.length; i++){ select.options[i].selected = false; } ", wele);
	}
	
■Samlple exec code
WebElement sitem = windowDriver.findElement(By.xpath("//select[@name='itemSel']"));
selectOption(windowDriver, sitem, "test object");

Thank you very much you are an angel. I’m working in a bank too with a very old system and I couldn’t do my job because of this bug. I wrote it in python and this finally works for me.
