Warning: "Expected static flag was missing" when rendering an empty object {} initially

[jortizhbr]

Basically, when I render the <JsonView /> component for the first time, my default value is an empty object {}. When that value changes React strict mode throws the following warning:

Warning: Internal React error: Expected static flag was missing. Please notify the React team. Error Component Stack

As a workaround I made the default value a nested object and that made the warning go away.

Here is a small component that triggers the warning:

const JsonViewer: React.FC = () => {
  const [json, setJson] = useState({});

  useEffect(() => {
    setJson({ "": { "": null } });
  }, []);

  return <JsonView data={json} shouldExpandNode={collapseAllNested} />;
};

I'm using react-json-view-lite version 2.3.0 and React 18.2.0.

Thank you for the report, I've found the root cause and fix it soon.

just released version 2.4.1 which fixes the warning.
