I am getting the following warnings which I assume prevent my app from loading its full functionality.

Warning: React does not recognize the toggleNode prop on a DOM element. If you intentionally want it to appear in the DOM as a custom attribute, spell it as lowercase togglenode instead. If you accidentally passed it from a parent ponent, remove it from the DOM element.

Warning: Received false for a non-boolean attribute focused. If you want to write it to the DOM, pass a string instead: focused="false" or focused={value.toString()}. If you used to conditionally omit it with focused={condition && value}, pass focused={condition ? value : undefined} instead.

Console Output

My guess is that your ToggleIcon is missing the onClick handler which should use the toggleNode handler (which you didn't filter out from props of ListItem).

    const ListItem = ({
      level = 0,
      hasNodes,
      isOpen,
      label,
      searchTerm,
      openNodes,
      toggleNode, // should be destruct here in favor of ToggleIcon
      onClick,
      matchSearch,
      ...props
    }) => (
// .....

    {hasNodes && <ToggleIcon on={isOpen} onClick={toggleNode} />}
