Solutions

1. Re-fetch the element by its node id; the DOM may have changed.
2. Verify the backend node id is still valid for the current document.

When it happens

Trigger: document.getElementById inside the click JS helper returns null for the element's id.

Common situations: Element id changed or element removed by page script between resolution and JS click fallback.
