"Unable to find element on closed window" error when finding an element after going to another url

Question

In the test I'm clicking a menu button that go to another page. Afterwards, when I try to find any element on page(The page exists, i can see it), the error 'unable to find element on closed window' keep appearing. I have tried directly getting the url and it works fine. It is when the test clicks a button and goes to another url that I get this error. Can anyone help me to resolve this in intern?

I'm using webdriver IEDriver 32bit, against IE11

Code :

define([
    "intern!object",
    "intern/chai!assert",
    "intern/dojo/node!leadfoot/Element",
    "intern/dojo/node!leadfoot/Server",
    "intern/dojo/node!leadfoot/helpers/pollUntil",
    "intern/dojo/node!leadfoot/keys",
    "require",
    "tests-config"
], function (registerSuite, assert, Element, Server, pollUntil, keys, require, config) {

    registerSuite({

        name: 'Test Suite Form Submissions',

        'Test Submit Form Step 1': function () {
            return this.remote
                .get(config.enter_doctor_url)
                .setFindTimeout(5000)

                .findByXpath("//span[text()='Create Case']")
                // goes to another url after clicking
                .click()
                .end()

               // error occurs here
               .findByXpath("//*[@id=\"js-wizard-eform\"]/fieldset[1]/table[2]/tbody/tr/td/div[1]/section[1]/label[2]/input")
               .pressKeys("John Doe")
               .end();
        }
    });
});

Console Output, Error:

Answer 1

The documentation does say

findByXpath(path: string): Promise.

Gets the first element in the currently active window/frame matching the given XPath selector.

So, if you want to find element in the previous window, you should use switchToWindow to make the window you want to find elements be active
