Showing data in Laravel Chatter Package is showing Undefined Variable Error - php

Question

I am working on adding a comment like stackoverflow using chatter discussion package by devdojo so here is the problem I am writing code to show comments but an undefined variable error is coming up.
Error Page ScreenShot
public function show(Chatterreply $chatterreply ,$id)
{
$chatterreplies = Chatterreply::where('chatter_post_id',$id)->get();
return view('chatter::discussion', compact('chatterreplies'));
echo "<pre>"; print_r('$chatterreplies'); die;
}
In Web.php route is
/*
* Post routes.
*/
Route::group([
'as' => 'posts.',
'prefix' => $route('post', 'posts'),
], function () use ($middleware, $authMiddleware) {
// All posts view.
Route::get('/', [
'as' => 'index',
'uses' => 'ChatterPostController#index',
'middleware' => $middleware('post.index'),
]);
// Create post view.
Route::get('create', [
'as' => 'create',
'uses' => 'ChatterPostController#create',
'middleware' => $authMiddleware('post.create'),
]);
// Store post action.
Route::post('/', [
'as' => 'store',
'uses' => 'ChatterPostController#store',
'middleware' => $authMiddleware('post.store'),
]);
//Adding Comments
Route::post('/reply/{id}', [
'as' => 'store',
'uses' => 'ChatterreplyController#store',
'middleware' => $authMiddleware('post.reply.store'),
]);
//showing Comment
Route::get('/reply/{id}', [
'as' => 'show',
'uses' => 'ChatterreplyController#show',
'middleware' => $middleware('post.show'),
]);

First, I would suggest putting your debugging statements (...print_r...) before the return statement in your controller action, this way :
public function show(Chatterreply $chatterreply ,$id)
{
$chatterreplies = Chatterreply::where('chatter_post_id',$id)->get();
echo "<pre>"; print_r('$chatterreplies'); die();
// or use the laravel helper
dd($chatterreplies)
return view('chatter::discussion', compact('chatterreplies'));
}
You should see the content of the $chatterreplies variable.
If this is ok, check your controller name in web.php because it seems that it should be ChatterReplyController#show instead of ChatterreplyController#show (is the R letter in ChatterreplyController#show capital or not ? ) if you're following the camelCase convention as in ChatterPostController#store for instance.
