Does anyone know what is wrong with my laravel form and controller? No errors were found

I am learning Laravel 8 and I know a lot about it. It doesn't show me any errors. Every time I submit the form it just refreshes the site and it doesn't redirect me anywhere. The data isn't saved to the table. I also used hasMany and belongs to in the user and product model. My controller looks like this

public function store(Request $request)
{
    $this->validate($request, [
        'name' => 'required',
        'brand' => 'nullable',
        'price' => 'required',
        'quantity' => 'required',
        'description' => 'required',
        'category' => 'required',
        'condition' => 'required'
    ]);    
    
    $request->user()->products()->create([
        'name' => $request->name,
        'brand' => $request->brand,
        'price' => $request->price,
        'quantity' => $request->quantity,
        'description' => $request->description,
        'category' => $request->category,
        'condition' => $request->condition,
    ]);

    return redirect()->route('products.index');
}

My Product model looks like this:

protected $fillable = [
    'name',
    'brand',
    'description',
    'price',
    'category',
    'quantity',
    'condition',
];
public $primaryKey = 'id';
public $timestamps = true;
protected $table = 'products';

public function user() {
    return $this->belongsTo(Business::class);
}
