Laravel route redirecting with data

Question

I have a basic route that looks like this:

Route::prefix('/group')->group(function () {
    // Some routes here
    Route::prefix('/{uuid}')->group(function () {
        // Some routes here
        Route::get('/user/{id}', 'Controller@preview')->name('view-user')->where('id', '[0-9]+');
    }
}

The logic is that I want the id to be only numerical value. What I want to do now is, to declare a redirection to this, if the value is non-numerical. Let's say the input of id is fs. In that case I would want it to redirect to id with value 1.

I tried using Route:redirect, but could not make it work. It looks something like this:

Route::redirect('/group/{uuid}/user/{id}', '/group/{uuid}/user/1')->where('id', '[^0-9]+');

I would prefer to put the redirect inside the groups, but it can be outside if this is the only way. Any help will be greatly appreciated.

What happens is, that I get a 404 error if I have the route redirect declared.

EDIT: I want to do it in the routes/web.php file. I know how to do it in the controller, but it is not what I need in the current case. Closures are not an option either, because that would prevent routes caching.

Following up on the comment

You can create a Route in routes/web.php file that catches non-digit ids and redirect this to 'view-user' with id=1

It would look something like this

Route::get('/group/{uuid}/user/{id}', function ($uuid, $id) {
  return redirect('view-user', ['uuid' => $uuid, 'id' => 1]);
})->where('id', '[^0-9]+');

// and then below have your normal route

Route::get('/group/{uuid}/user/{id}', 'Controller@preview')->name('view-user')->where('id', '[0-9]+');

Update

Following you comment that you do not want to use closures.

Change the "bad input route" to

Route::get('/group/{uuid}/user/{id}', 'Controller@redirectBadInput')->where('id', '[^0-9]+');

and then add the method in class Controller:

public function redirectBadInput ($uuid, $id) {
  return redirect('view-user', ['uuid' => $uuid, 'id' => 1]);
}
