Lumen - FatalThrowableError Call to a member function file() on null

I am trying to insert values into my file table and I am getting a error. FatalThrowableError Call to a member function file() on null.

Inset.php Model 

namespace App;

use Illuminate\Database\Eloquent\Model;

class Inset extends Model
{
    /**
     * The table associated with the model.
     *
     * @var string
     */
    protected $table = 'insets';

    public function file()
    {
        return $this->hasMany('App\File');
    }
}

File.php Model

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class File extends Model
{
    /**
     * The table associated with the model.
     *
     * @var string
     */
    protected $table = 'files';
    protected $fillable = ['file_name','file_content', 'insets_post'];

    public $timestamps = false;

    public function inpost()
    {
        return $this->belongsTo('App\Inpost');
    }
}

FilesController.php Controller

<?php
/**
 * Created by PhpStorm.
 * User: Kacper
 * Date: 28.02.2018
 * Time: 14:00
 */

namespace App\Http\Controllers;

use App\File;
use App\Inset;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Crypt;

class FilesController
{
    public function showAll(Request $request)
    {
        return File::all();
    }

    public function show($ID_inset)
    {
        return File::findOrFail($ID_inset);
    }

    public function insert(Request $request)
    {
        $inset = Inset::find($request->input('inset_id'));
        $file =$inset ->file()->create([
            'file_name' => $request->input('file_name'),
            'file_content' => Crypt::encrypt($request->input('file_content'))
        ]);
        $file->save();
    }
}

Error:

Your Code

$inset = Inset::find($request->input('inset_id'));

Is returning null that's why it is Throwing this error.

if you want to avoid error you can do this like 

$inset = Inset::find($request->input('inset_id'));

 if($inset){
    $file =$inset ->file()->create([
        'file_name' => $request->input('file_name'),
        'file_content' => Crypt::encrypt($request->input('file_content'))
    ]);
    $file->save();
 }

Hope this helps
