Category	Accessibility
Scope	Per-page
Severity	error

Solution

IDs referenced by ARIA attributes (aria-labelledby, aria-describedby, aria-controls, etc.) must be unique on the page. Duplicate IDs cause assistive technology to potentially reference the wrong element. Rename duplicate IDs to be unique.
