Can not read property ownerDocument of null

I am getting TypeError: Cannot read property 'ownerDocument' of null even if all the required props are passed to Container and element.

Line Number: 429 File: SortableContainer/index.js

You have to wrap your items with an element;

error;

indexes.map((index: number) => (
   <div key={`${name}-${index}`}>
      ...
   </div>
))

Fix;

<div>
   {indexes.map((index: number) => (
     <div key={`${name}-${index}`}>
       ...
     </div>
   ))}
</div>

One other thing to look out for - if you wrap an element whose render exits early and returns undefined/null when there are no items you’ll also get this error.
