title: Invalid ARIA Prop Warning
layout: single
permalink: warnings/invalid-aria-prop.html
---
The invalid-aria-prop warning will fire if you attempt to render a DOM element with an aria-* prop that does not exist in the Web Accessibility Initiative (WAI) Accessible Rich Internet Application (ARIA) [specification](https://www.w3.org/TR/wai-aria-1.1/#states_and_properties).
1. If you feel that you are using a valid prop, check the spelling carefully. `aria-labelledby` and `aria-activedescendant` are often misspelled.

2. React does not yet recognize the attribute you specified. This will likely be fixed in a future version of React.
