How to scroll to element with Selenium and Node.JS driving Firefox?

I'm trying to scroll to a link element on the page and click it. The following solution works for Chrome and IE, but not for Firefox. How could I fix this? Is there any other approach to it?

function clickByLinkTextScroll(text){
        driver.findElement(By.linkText(text)).getLocation().then(function (location) {
            driver.executeScript("window.scroll(0," + location.y + ");");
            driver.sleep(300);
            driver.findElement(By.linkText(text)).click();
        });
};

When I run it against Firefox I get the following output:

UnknownCommandError: GET /session/ad17a19d-782b-4706-b1d7-b56f0139b252/element/5c5e0c3d-1861-432c-b402-b6a010c2f268/location did not match a known command

As Sudharsan Selvaraj suggested, I used the following and it did the job nicely:

function clickByLinkTextScroll(text) {
    element = driver.findElement(By.linkText(text));
    driver.executeScript("arguments[0].scrollIntoView()", element);
    driver.sleep(300);
    element.click();
};
