Selenium C# IJavaScriptExecutor throws error but JS is fine

I'm using Selenium C# to test a pretty complex web UI in Internet Explorer 11. As you might know, Selenium's Click() tends to not work in which case inserting a JS click method is necessary. I'm running the dynamically generated script below using

(IJavaScriptExecutor) driver).ExecuteScript(script). Here is the script :

let iFrame = document.getElementById("dkwframe").contentWindow.document;
let element = iFrame.querySelector("[id*='_ImgLnkNewPage_LinkButtonControl']");
element.click();

The script works fine when I execute it directly in the IE console, but when executing with it Selenium I get this :

System.InvalidOperationException : Error executing JavaScript (UnexpectedJavaScriptError)

The IE console is empty so I don't think it's even trying. Also, switching browser isn't an option.

Thanks for the help

Maybe the script is being executed before the page is fully loaded ,try to put it in a page ready event ha dler like that

window.onload = function() {
    et iFrame = document.getElementById("dkwframe").contentWindow.document;
    let element = iFrame.querySelector("[id*='_ImgLnkNewPage_LinkButtonControl']");
    element.click();
}

Or you can check if the fully loaded with :

if (document.readyState === 'complete') {
}
