laravel 5.5.44 post router throws 302 Found Error

Facing 302 Found error when trying to update using a post method in a route.

Route

Route::post('update_article/{id}', 'ArticleController@update_article')->name('articles.update');

Edit Form Blade

{!! Form::model($article, ['route'=>['articles.update', $article->id], 'method' => 'post', 'class' => 'form-horizontal form-stripe']) !!}

Controller

public function update_article(Request $request, $id)
    {
        $data = Article::find($id);
        $data->title = $request->input('title');
        $data->description = $request->input('description');
        $data->user_id = Auth::id();
        $data->status = $request->input('status');
        $data->save(); 
        return redirect()->route('articles.index');
    }

Using POST for updating instead of PUT as i am using summernote. When i use PUT, large description gets truncated. In summernote it states that it may happen if i do not use POST method.

And there is also a default route just before the update_article route for articles resources as:

Route::resource('articles', 'ArticleController');

Note: csrf token is sent as _token params in the post operation. Cannot find any solution yet. Is there anything I am missing?
