when I go to the url that matches, component is not getting rendered react-routes

Question

I go to the url that matches the path or a route and the component in not getting rendered. I also have wrapped every thing with BrowserRouter in index.js file as well. Can't figure out the problem here. Help me pls.

Here is code

import { Route, Switch } from "react-router-dom";

<Switch>
        <Route
          path="comments/:curPage"
          render={(props) => <List {...props} comments={comments} />}
        />
        <Route path="test" exact component={Test} />
      </Switch>

Here is index.js file

ReactDOM.render(
  <BrowserRouter>
    <React.StrictMode>
      <App />
    </React.StrictMode>
  </BrowserRouter>,
  document.getElementById("root")
);

My package.json file

{
  "name": "client",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@testing-library/jest-dom": "^5.14.1",

      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

When I go to the url comments/1 The content in <List /> component is not getting rendered. Why?
