autoCapitalize and autoCorrect Config

A username field passes a boolean to autoCapitalize instead of an enum string.

Codejavascript
function UsernameField({ value, onChangeText }) {
  return (
    <TextInput
      value={value}
      onChangeText={onChangeText}
      placeholder="Username"
      autoCapitalize={false}
      autoCorrect={false}
    />
  );
}

What is wrong with the autoCapitalize prop?
