To fix this issue, there are several steps you can take:
1. Check the URL
2. Check for Syntax Errors
If the URL looks correct, the next step is to check your code for syntax errors. Look for missing semicolons, mismatched parentheses, and undefined variables. Use a syntax checker tool like JSLint or JSHint to identify any syntax errors.
3. Debug Your Code
If there are no syntax errors, use your browser's developer console to debug your code. Look for any log messages or error messages that may provide clues as to what's causing the error. You can also use breakpoints to stop your code at specific points and inspect variables and other data.
4. Check for Browser Compatibility Issues
If none of the above steps work, check for browser compatibility issues. Make sure your code works on all popular browsers, including Chrome, Firefox, Safari, and Internet Explorer. You can use services like BrowserStack or Sauce Labs to test your code on different browsers and devices.
5. Remove the Event Handler
