react snap giving error with react routes

Question

React snap and react routes don't seem to work properly together and giving errors . Here is the error

I used react snap with a simple web app which had no routes in it and there was no error postbuild and I could see the 200.html file generated but with the app that we have in production and has numerous routes in app.js seems to throw these errors .I could not figure out as why there are timeout errors in this case and how we can overcome this .

Our routes are somewhat similar to this "react-snap and react-router together make a problem"

Answer 1

It's too late I think but in case if somebody see this, I detected that route without "path" is causing that problem.

Here is error fragment

so if we look at the code fragment

  export default function App() {
      return (
        <div className="App">
          <Route path="/article/:id">
            <Article />
          </Route>
          <Route path="/cart/">
            <CartPage />
          </Route>
          <Route path="/order/:status">
            <OrderStatus />
          </Route>
          <Route> <----------------<<<< without PATH="someRoute"
            ////////////////////////////////////
            // this was causing that error!!! //
            ////////////////////////////////////
            <Error404 />
          </Route>
        </div>
      );
    }

If I comment that part everything is working perfect! Hope it helps ;)
