Answer 1

Some of the array elements are null and the method used to delete the file only accepts the string type (the file path), so the error is returned. Try checking its elements before passing the array. If you do not want to check all the fields and all these fields are required in your business logic, try to make these columns required in your model/table.

Ex:

public function destroy($id)
{
    $video = Video::where('id' , $id)->first();
    $convertedVideos = Convertedvideo::where('video_id' , $id)->get(); 
    foreach($convertedVideos as $convertedVideo){
        
        // array_filter will remove all elements equals to FALSE
        $paths = array_filter([
            $convertedVideo->mp4_Format_240,
            $convertedVideo->mp4_Format_360,
            $convertedVideo->mp4_Format_480,
            $convertedVideo->mp4_Format_720,
            $convertedVideo->mp4_Format_1080,
            $convertedVideo->webm_Format_240,
            $convertedVideo->webm_Format_360,
            $convertedVideo->webm_Format_480,
            $convertedVideo->webm_Format_720,
            $convertedVideo->webm_Format_1080,
            $video->image_path
        ]);

        Storage::delete($paths);
    }
    $video->delete();
    return back()->with('success' , 'Completed');
}
