The prop value with an expression type of JSXEmptyExpression could not be resolved.

Can you share the code that this crashed on?

[quisido]

I don't think I still have it, but it was something like this:

function MyComponent(): ReactElement {
  const buttonProps: (Required<Attributes> & ButtonHTMLAttributes<HTMLButtonElement>)[]= [
    {
      children: 'test',
      key: 'test',
      onClick: (): void => {
        return;
      },
    },
  ];

  return <>
    {
      buttonProps.map(
        ({ key, ...props }: Required<Attributes> & ButtonHTMLAttributes<HTMLButtonElement>): ReactElement =>
          <button key={key} type="button" {...props} />
    }
  </>;
}

key may not have been destructured at the time of the crash, though; and the type prop may have been missing.

Sorry that I can't provide an exact copy. Hope this helps.

So you can't reproduce the crash anymore?

[quisido]

I haven't tried. I have since fixed it in my codebase and do not have the opportunity to re-break it. I was hoping the information in the OP was enough.

<button {...props} /> where props is Required<Attributes> & ButtonHTMLAttributes<HTMLButtonElement> is as specific as I can be for the time being.

Unfortunately the snippet above doesn't seem to parse.

[ljharb]

ok, i was able to fix the parse error, but it passes on the latest eslint-plugin-react. Are you sure you've got the latest version of that, and jsx-ast-utils, installed?

This also seems like the same as #107, so I'll close, unless we can reproduce it. Thanks for filing!
