In Webflow, why does the code "alienShips.addEventListener('click', debunk);" result in a "Uncaught TypeError: alienShips.addEventListener is not a function" error message?

When you see the "Uncaught TypeError: alienShips.addEventListener is not a function" error message in Webflow, it typically means that the variable "alienShips" is not an object that has the addEventListener method. Here are a few possible reasons why this error might occur:

1. Incorrect Variable Assignment: Double-check that the "alienShips" variable is correctly assigned to the DOM element you intend to add the event listener to. Ensure that the element exists in the HTML structure and that the variable is referencing it correctly.

2. Element Selection Issue: Verify that you are correctly selecting the element with the "alienShips" ID or class using the appropriate selector method in JavaScript (e.g., getElementById, getElementsByClassName, querySelector, etc.). It's possible that the element is not being selected properly, resulting in the error.

3. Timing Issue: Consider whether the code is being executed before the element with the "alienShips" ID or class has been loaded into the DOM. If the JavaScript code runs before the relevant HTML element exists, the code will not be able to find the element and create the event listener, resulting in the error. To solve this issue, ensure that the JavaScript code is executed after the relevant HTML element has been loaded or use event delegation to listen to events on parent elements.

4. Conflict with Frameworks or Libraries: If your project uses other JavaScript frameworks or libraries, there may be a conflict that prevents the addEventListener method from being recognized. Check for any conflicting code or libraries that might interfere with Webflow's built-in JavaScript functionality.

To troubleshoot and resolve the error, use the browser's developer tools to inspect the "alienShips" variable, its value, and determine its data type. Ensure that it is a valid DOM element with the addEventListener method available.
