The parameter in the URL is returning undefined

Question

I'm trying to reset the password via email, until now I managed to send the link and register a token in the database. Now I want to check that token, too see if it's the same one, but I'm getting undefined.

Here is what I have in the database:

userRouter.get('/reset/:token', expressAsyncHandler(async (req, res) => {
  console.log(req.params)
  const user = await User.findOne({
      resetPasswordToken: req.params.token,
      resetPasswordExpires: {
        $gt: Date.now(),
    },
  });
  if (user) {
    console.log('token matched')
    res.status(200).send({
      message: 'password reset link ok'
    })
  } else {
    console.log('password reset link is invalid or has expired');
    res.json('password reset link is invalid or has expired');
  }
})
);

The console.log(req.params) is returning undefined

I will also post the frontend code, because I don't really know where the problem is.

In the userActions.js:

export const checktoken = (token) => async (dispatch) => {
  dispatch({ type: USER_RESET_PASSWORD_REQUEST, payload: { token } });
  try {
    const { data } = await Axios.get(`/api/users/reset/${token}`);
    dispatch({ type: USER_RESET_PASSWORD_SUCCESS, payload: data });;
    localStorage.setItem('userInfo', JSON.stringify(data));
  } catch (error) {
    dispatch({
      type: USER_RESET_PASSWORD_FAIL,
      payload:
        error.response && error.response.data.message
          ? error.response.data.message
          : error.message,
    });
  }
};

In the userReducer:

export const userForgotPasswordReducer = (state = {}, action) => {
    switch (action.type) {
      case USER_FORGOT_PASSWORD_REQUEST:
        return { loading: true };
      case USER_FORGOT_PASSWORD_SUCCESS:
        return { loading: false, token: action.payload };
      case USER_FORGOT_PASSWORD_FAIL:
        return { loading: false, error: action.payload };
      default:
        return state;
    }
  };

And in the resetPassword:

const userCheckToken = useSelector((state) => state.userCheckToken);
  const params = useParams();
  const tokennr = params.token;
  const { loading, error } = userCheckToken;
  const dispatch = useDispatch();

  useEffect(() => {
    dispatch(checktoken());
  }, [dispatch, tokennr]);

I wonder, where the problem might be, because I can't find a way to get the token in the database.
