aria-label={noText ? children : undefined}

Warning: Failed prop type: Invalid prop aria-label of type array supplied to Button, expected string.
checkPropTypes.js:20

The children prop is an array of all children. The button element's content model accepts all phrasing content except interactive content. The children prop could rightfully contain components/elements in this context.
