This may be caused by reactjs/react-transition-group#469

We're in the process of setting up a fork that works without findDOMNode. Hopefully this resovles those issues.

i think this bug is from functional components , i use functions and before that , i have no errors

Out of curiosity: Do you even use transition handlers e.g. onExited and use the node argument?

it is my Drawer

You could've also passed your own onExited handlers which is why I asked. Just want to collect some data points if people actually use those.

@nimahkh By any chance, can you provide a minimal reproduction example?

onExited is about Menu or Transition components , the problem is Drawer , so onExited and another Exit Props , will not work on it , as you can see in my code above , i have no Menu Component, some times i have this problem and some times , every thing is ok

@nimahkh Could you provide a minimal reproduction? We won't be able to help more otherwise.

i was writing in codesandbox and then it crash and throw me out . but something is interesting , my code works on sandbox , i dont know what is going on

[nimahkh]

solved

it was because of lazy and suspense . i dont know why , but when i remove suspense and load components normal , it solved

[nimahkh]

i change my routers like this , and everything is perfect now

import React, { lazy, Suspense } from "react";
import ReactDOM from "react-dom";
import { MemoryRouter as Router, Route, Switch } from "react-router-dom";

import Home from "./home";
const Post = lazy(() => import("./post"));

function App() {
  return (
    <Router>
      <div className="App">
        <Switch>
          <Route path="/" exact component={Home} />
          <Route path="/:id" component={WaitingComponent(Post)} />
        </Switch>
      </div>
    </Router>
  );
}

function WaitingComponent(Component) {
  return props => (
    <Suspense fallback={<div>Loading...</div>}>
      <Component {...props} />
    </Suspense>
  );
}

const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);
