Invalid ARIA Prop Warning single 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.

  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. However, React currently strips all unknown attributes, so specifying them in your React app will not cause them to be rendered
