No such element: Unable to locate element OpenQA.Selenium in C#

Question

I am facing this exception:

OpenQA.Selenium.NoSuchElementException: 'no such element: Unable to locate element: {"method":"css selector","selector":"#MuliCloudAccountSelector"}

My Code:

driver.FindElement(By.Id("MuliCloudAccountSelector")).Click();

My HTML:

<div id="MuliCloudAccountSelector" class="antd-pro-src-components-page-header-wrapper-multi-account-selector-antpopover" style="border: 1px solid rgb(217, 217, 217); margin-left: 6px; margin-right: 10px; height: 40px; float: left; min-width: 24px; border-radius: 4px; max-width: 316px; overflow: hidden;">

What am I missing?

Answer 1

You need to wait for the element to be clickable:

var wait = new WebDriverWait(drive, TimeSpan.FromSeconds(30));
var div = wait.Until(ExpectedConditions.ElementToBeClickable(By.Id("MuliCloudAccountSelector"));

div.Click();

There is likely a race condition occurring between Selenium and the browser. You are finding the element before the element is rendered in the page.
