Site works fine in homestead, won't work using forge, logs a "array_key_exists() expects parameter 2 to be array, null given"

do you have a stack trace? without it, it's next to impossible to find out where this error is coming from.

I think this is it:

What's in VideoController.php index function?

namespace App\Http\Controllers;

use App\Video; use Illuminate\Http\Request; use Carbon\Carbon; use View;

class VideoController extends Controller {

public function index()
{
    $res = Video::orderBy('date_of_message', 'DESC')->get()->first();
    $name = array_pull($res, 'id');
    $videos = Video::all()->sortByDesc('date_of_message');
    return redirect()->route('show', [$name]);

   
}


   public function create(Request $request)
{
    $video = new Video;
    $video->title = $request->title;
    $video->description = $request->description;
    $video->video_number = $request->video_number;
    $video->date_of_message = $request->date_of_message;
    $video->nice_date = $video->date_of_message->toFormattedDateString();       

   

    $video->save();
    return redirect('/');
}

   public function store(Request $request)
{
    //
}


public function show(Video $video)
{
    $videos = Video::all()->sortByDesc('date_of_message')->except($video->id);
    
    return view('videos.show', compact('video', 'videos'));

}

    public function edit(Video $video)
{
          
   $video = Video::find($video->id);


   return View::make('videos.edit', compact('video'));

    

    
}

   public function update(Request $request, Video $video)
{
 
            
    $video->update([
            'title' => $request->title,
            'description' => $request->description,
            'date_of_message' => $request->date_of_message,
            'video_number' => $request->video_number,
            'nice_date' =>  Carbon::parse($request->date_of_message)->toFormattedDateString()    
        ]);

        return redirect ('/');
         }


 public function destroy(Video $video)
{
    $video->delete();
    return redirect ('/');
}

}

This is the route that the index function redirects to. I think I made a mistake by putting $name in brackets like an array. But if I take it out of brackets it still fails.

Route::get('/videos/display/{video}', 'VideoController@show')->name('show');

Solved: Ok this was a rookie mistake on my part; my index view shows existing records in the DB, which needed to be added to the production side DB. Once they were in there, it worked. Sorry. Thanks for pointing me toward the index method. I did find that array mistake there and that fixed part of the problem!

you might want to start using firstOrFail() instead of first()

This will throw an exception if nothing was found (which you can then catch and handle any way you want to).

This would then have thrown a 404 error (which would be easier to find / fix)

$res = Video::orderBy('date_of_message', 'DESC')->get()->firstOrFail();

Thanks. I'm still a newbie with laravel, and active model for that matter. I appreciate the guidance!

I'm using the latest tech code in my site to help in performance and optimization. If you have new one code, then kindly share it.

I have a Wordpress site developed a year back. Now i want plan to move over laravel. Is that possible i can do and also keep my SEO performance and ranking? Thanks.

I also have a modded games website for Android. I also have the same question as @muhsarim?

I have a WordPress site on 10th Class Result 2021 developed last year. I want to move over Laravel and keep my SEO ranking? Can that be done, or does this require some technical expertise in order for it all work out smoothly?"

Finally, I am able to solve the issue on my site by using the first()
