System.NullReferenceException in Selenium because not able to find a web element present on the pagesource IN SELENIUM

Question

Probably many of you have faced the classic error System.NullReferenceException and managed to sort that out.

I have a popup that is displayed with a text box and a button that I need to click, I can see both elements printed out by debugging using

Debug.Print((webDriver.PageSource));

However my selenium code is not able to find them to send Keys or click.

Using IEDriver 3.12 browser: IE v11

The element I need to find is the id "uxEffectiveDateToApply"

ANYBODY HAS AN IDEA HOW TO FIND IT AND SEND KEYS???

<BODY class=popupBGColor style="CURSOR: auto">
<FORM name=form1 id=form1 onsubmit="if (typeof(CommonUtils.okToSubmit) == 'function' &amp;&amp; !CommonUtils.okToSubmit()) { return false; }" action=/PWFE/(S(0eycnhf2h5iz3o1ssojspyno)F(0j_gLwVPxiu2GKnplULS3mGfjTFtlwmzB_si8-zlKxWyEELwfFjmsI22iV1CHszlEIBJMQC_2-ZVisvN9SXno67Tq9XCHr5sVaCLAUSOcb1qoBT781fyZUpg3tqiN4YFSK7vNYLlGsVRfKQc8UeQLTwTCgdVj0ZDZ9uJ_4_BBCWXaLtOv2NYnGm66vvhXP7v0))/Common/Popups/ModifyPolicyPopup.aspx method=post>

Hi Prany, it is too long and does not let me paste it here, but snipped with the HTML code is shown on the original question — Esteban Balvin, Jun 11 '18 at 04:44
@EstebanBalvinRuiz What is your exact question? `find a web element present on the pagesource`, or `to send Keys` or `click`? — undetected Selenium, Jun 11 '18 at 06:46
Hi, before passing any text to the text box in the popup, first you have to switch to popup box and then send text, the same way you have to do for a button click. Just for referance.[popup](https://stackoverflow.com/questions/19403949/how-to-handle-pop-up-in-selenium-webdriver-using-java) *driver.switchTo().alert().sendKeys("Text");* and *driver.switchTo().alert().accept();* — Priya P, Jun 12 '18 at 06:28
